EXPERIMENT 1: MOLECULAR MODELS OF NEUTRAL MOLECULES In this experiment, you will predict the three-dimensional geometry of a series of neutral molecules using the VSEPR theory. PROCEDURE Part 1: The Periodic Table 1. Use the Periodic Table of Elements to determine the elemental symbol, group number, and valence electrons for the elements listed in Table 1 on the Experiment 1 Data Sheet. Record this data in Table 1.

2. Use colored pencils and the data in Table 1 to sketch a Lewis Dot Structure for each element in Table 1 on the Data Sheet. ©2018, eScience Labs Part 2: Construction of Molecules 1. Now, construct the three-dimensional geometry for the molecules listed in Table 2 on the Data Sheet. While you are constructing your molecules, keep the following points in mind: • Nature “loves†symmetry, which means equal bond lengths and angles. • Electrons prefer to be as far apart from each other as possible without disrupting the symmetry too drastically. • Lone pairs take up more space because they are not confined by bonds, and are localized. 2.

Look at Table 2 on the Data Sheet, and fill in the bond angles for each molecule you will be building. Hint: Use the column in Table 2 on the Data Sheet labeled “Structure†to determine the molecular geometry. 3. Using colored pencils, make a Lewis Dot Structure sketch for each molecule in Table 2 you will be building. 4.

Gather as many marshmallows and toothpicks you will need for building your first molecule (carbon dioxide). Hint: You will need two marshmallows for the oxygen (O), and one marshmallow for the carbon (C). 5. Using the permanent marker, label the miniature marshmallow with the elemental symbol for each atom in your molecule (Figure 19). 6.

Refer to the first column in Table 2 to determine the central atom in your molecule. 7. Connect the atoms together with toothpicks. 8. Compare your model with the diagram of the Linear molecular geometry in Table 2.

9. Use your protractor to verify that you have constructed your molecule with the correct bond angles. 10. To determine the angle between your atoms, place the center of the protractor on the central atom, and align the base with a bond (Figure 19). Then measure the angle.

When in doubt, think “Should this angle be bigger or smaller than 90°?†11. If your bond angles are incorrect, remove the toothpicks from the marshmallows, construct the molecule again, and use your protractor to verify that you have constructed your molecule with the correct bond angles. 12. Follow the above procedures for each molecule in Table 2. 13.

When you are finished, take a picture of the molecules and send the images to your instructor. Make sure you identify yourself, the name of the lab, and any other necessary identifying information. Figure 19: To satisfy the octet rule, the linear carbon dioxide molecule has double bonds. Note, the bond angles should be 180 degrees. ©2018, eScience Labs Data Sheet Experiment 1 Data Sheet Table 1: Lewis Dot Structures Element Symbol Group Number Valence Electrons Lewis Dot Structure Hydrogen Carbon Chlorine Aluminum Oxygen Fluorine Neon Nitrogen ©2018, eScience Labs Data Sheet Experiment 1 Data Sheet Table 2: Molecular Models Molecule (central atom is underlined) Sketch of Lewis Dot Structure Shape Name Structure Bond Angle CO2 Linear AlCl3 Trigonal Planar H2O Bent NH3 Trigonal Pyramidal ..

When Aero Performance was created 12 years ago, the company faced little competition, and a robust airline market seemed to present an unlimited potential for growth. Unfortunately, industry economics coupled with cost-cutting measures by airlines and new competition from similar airline service companies means that Aero’s business performance has stabilized, and the company has actually experienced losses in certain specialized areas.

One of these areas is the sales of the company’s technologically advanced equipment. Airline companies as well as the owners of corporate jets have delayed the purchase and installation of Aero’s advanced electronic equipment. Mike Martinez, manager of the technology upgrade unit, faces a tough decision. With a significant downturn in his unit’s work, he must lay off one employee. The decision is made particularly difficult because all employees of the unit are qualified employees with average or better work records.

Additionally, each employee has a unique personal background directly affecting his or her work life. A summary of the background and work record of each of the four employees follows. No question, Martinez faces a difficult decision. Gary Meadors is married and has two children in high school. He lives modestly in order to send his kids to college.

His wife works evenings at a convenience store to assist with family expenses. Meadors has worked nine years with Aero Performance, six years in airline maintenance and three years in the technology upgrade unit. He has learned airline technology largely through technical articles, trade journals, and on-the-job experience. His performance evaluations are average, and he is considered a consistent and reliable employee. His attendance and company loyalty are exceptional.

Brenda Baldwin is the only woman in the technology upgrade unit. She is a single mother with a child in elementary school. Brenda has three years of service with Aero Performance, all in Martinez’s unit. She joined the company after obtaining an airline technology degree from a well-respected four-year university. Brenda continues to take evening classes in her field and seems to have, according to Martinez, “the most potential for growth in the company.†However, her performance has slipped the past year, and she has been counseled for an attendance problem.

She has felt somewhat resented as a female in a traditionally male-dominated industry. Udit Chopra is a dedicated employee. In fact, everyone says he is “married to his job.†He will work long hours to complete technical installations and is regarded as a perfectionist. Udit has a college degree in marketing but has found his home in airline technology. He possesses an excellent ability to persuade Aero Performance customers to upgrade their technology systems.

Udit drives a new BMW and is believed to come from a wealthy family. Craig Cottrell joined Aero Performance three years ago, having been hired away from a competitor. He has a total of 12 years of experience in the airline service industry. Craig has a complete understanding of airline technology. Cottrell’s work performance the first two years with Aero Performance was barely average; however, his work record the past year was evaluated as very high.

Currently, he is the top performer in the unit. There has been work friction between him, Baldwin, and Chopra over the selection and installation of cockpit instruments. Mike Martinez must make his decision by this Friday. Aero Performance will grant the laid-off employee a severance package to assist transition to other employment. Martinez is committed to aiding his employee in finding another job in the airline service industry.

Paper for above instructions

Case 11: Someone Has to Go: A Tough Layoff Decision

1. What criteria should be used to determine potential layoff candidates?

In the context of layoffs, establishing clear criteria is crucial to ensure fairness and maintain morale among remaining employees. The criteria for selecting potential layoff candidates should include performance evaluations, skills and qualifications, collective experience, and business needs.
1. Performance Evaluations: Employees with higher performance ratings should preferably stay employed. Performance metrics can include productivity, efficiency, and contribution to team goals (Baker et al., 2019).
2. Skills and Qualifications: Assessing unique skills that are crucial for the company’s current needs is vital. For example, Udit's strong persuasion skills in upgrading technology provide tangible benefits to Aero Performance. Personnel with specialized skills that contribute more directly to revenue generation or are critical to business operations should be prioritized (Rogers & Pugh, 2020).
3. Experience and Tenure: Longevity with the company can reflect loyalty, but it should not be the sole factor. Differences in tenure provide insight into the depth of experience an employee brings. For example, Gary’s longer tenure could suggest stability and reliability, but his performance metrics also warrant consideration (Smith et al., 2021).
4. Alignment with Business Strategy: Finally, candidates who better align with the strategic direction of the company should be prioritized. As Aero Performance shifts focus possibly toward its technology upgrade unit amid declining sales, retaining employees who can assist in that pivot is crucial (McGuire, 2022).
Overall, a balance of objective performance metrics combined with strategic business needs will help streamline the process.

2. What emphasis, if any, should be given to non-job-related factors such as personal problems or a spouse’s need to work?

Non-job-related factors such as personal circumstances should be handled sensitively but are not ideal for making layoff decisions. Fairness and objectivity are paramount in such decisions. Considering non-job-related factors could risk perceptions of favoritism, affecting morale and the company culture (O'Connor, 2018).
However, acknowledging these factors in a holistic view can foster empathy in decision-making. For instance, Brenda's single motherhood incurs considerable stress, which can be weighed against her recent performance decline. Yet, it’s important to ensure that such considerations do not overshadow essential professional criteria (Carson & Harris, 2021).
While Martinez should maintain a compassionate approach during layoffs, prioritizing consistent job-related factors provides a clear rationale for the decision, minimizing the risk of resentment among other staff members.

3. What should be included in a severance package for laid-off employees?

A well-structured severance package is essential for supporting laid-off employees during their transition. A comprehensive severance package should include:
1. Monetary Compensation: Severance pay, often based on tenure, is essential for immediate financial relief. Typical packages range from one week to several months of pay, depending on the organization’s policies (Johnson, 2019).
2. Health Benefits: Continued health insurance coverage is vital. Companies should provide extended coverage options such as COBRA, allowing laid-off employees to maintain their medical insurance (Steinberg, 2020).
3. Job Placement Assistance: Offering services like resume writing, interview coaching, and access to job placement resources can facilitate a smoother transition for laid-off employees (Nguyen, 2021).
4. References and Network Connections: Committing to providing positive references can significantly aid former employees in securing new jobs. Providing them opportunities to network through alumni events can enhance employment prospects (Taylor, 2022).
By including these elements, Aero Performance can mitigate the adverse effects of layoffs and reinforce a positive employer brand even during difficult times.

4. How long should the severance package last?

The duration of the severance package should ideally correlate with the employee’s length of service and the financial state of the company. A standard approach is to offer one to two weeks of severance pay for every year of service (Pearson & Warner, 2018).
For example, if Craig, with 12 years of service, is laid off, he could receive up to 12-24 weeks of compensation. This policy not only aligns with common practices but respects the loyalty of employees who have dedicated long years to the company (Costa & Tranquili, 2021).
Furthermore, including clear terms about duration in the severance agreement can ensure that expectations are managed effectively.

5. Are there any potential legal implications in Martinez’s decision?

Yes, there are several legal implications associated with layoffs. First, discrimination laws come into play; if the layoff disproportionately affects a certain demographic group, the company could face legal challenges under Title VII of the Civil Rights Act (Dunham & Tucciarone, 2018).
Second, contractual obligations may exist. Employees with contracts or union agreements may have specific rights, and neglecting these can lead to litigation (Feldman, 2019).
Lastly, whistleblower protections and employee privacy rights are vital to consider. If any employee has previously reported misconduct or unsafe practices, targeting them for layoffs could result in legal ramifications (Graham, 2020).
Maintaining transparency, adhering to legal requirements, and ensuring that the criteria for layoffs are fair can significantly diminish risks.

6. How would you handle the termination interview?

Handling termination interviews requires professionalism and empathy. Here are key strategies to implement:
1. Prepare Thoroughly: Gather all necessary documentation and outline the rationale for the layoff to present a clear picture to the employee (Braton & Martocchio, 2021).
2. Choose an Appropriate Setting: Conduct the interview privately and in a quiet place to maintain confidentiality and respect (Marin, 2021).
3. Be Direct Yet Compassionate: Clearly explain the reasons for the decision without sugar-coating. Express empathy for the employee’s situation (Culley, 2020).
4. Provide Support Information: Share details about the severance package and any additional resources available, and be responsive to any questions they may have (Rosen, 2022).
This approach can help ease the emotional burden of terminations and leave employees feeling respected, even in challenging circumstances.

7. When you began this assignment, what were your initial thoughts of who should remain employed and who should be terminated? Explain your answer.

Initially, it seemed that Udit and Craig were the strongest candidates for retention due to their distinct, valuable skills in technology upgrades and their recent performance records. Brenda, despite her potential, presented performance issues. Gary’s longer tenure suggested loyalty but was overshadowed by lesser performance metrics.
However, with deeper analysis into performance history, personal circumstances and potential business needs, it became clear that evaluating the contributions holistically rather than simply by surface qualifications is essential (Marr, 2019). Retention decisions should reflect a mix of immediate performance needs with long-term growth and technology adaptability.

8.1 After completing this assignment, how have your thoughts changed from your initial reactions and conclusions?

The intricacies surrounding layoffs showed me the importance of a structured, legally sound approach. It’s critical to weigh employee value from multiple perspectives to ensure a fair process while aligning with business needs.
This has underscored for me the importance of empathy in personnel management. For my future career, I have learned to balance objective criteria with empathy, ensuring fairness, which is essential in maintaining a positive and productive workplace culture (Landers, 2022).
