Question
Classify the following statements as true or false:
1.) Ionization energy values are always positive.
2.) Electron affinity is the amount of energy required to add an electron to a neutral atom to form an ion with a (-1) charge.
3.) Electron affinity is based on the observation that electrons are attracted to other electrons.
4.) Electron affinity provides an indication of the relative tendency of an atom to form an anion with a (-1) charge.
5.) Ionization energy is the amount of energy required to remove an electron from an atom.
6.) Electronegativity values are always positive.
Requirments:
1. Show all Reasoning.
2. Clearly explain your answer.
Explanation / Answer
1)
True..
Ionization energy is defined as the amount of energy needed to "remove" and electron from a neutral atom. It is always positive by convention, the energy provided to the atom is positive. It is ALWAYS necessary to "give" energy to the atom since it is a stable system. The electrons DON"T WANT TO LEAVE the atom.
2)
True.
It is the energy that the atom releases or absorb if one electron is added to its electronic shell.
3)
False
as it is a tendency to accommodate electrons in their shells by atoms
4)
True..
if the energy of the ion formed (always -) is more stable than the atom, the Electron Affinity is positive. If the ion is unstable, the Ea will be negative..
so convention of electron affinity can give an idea about ion formed.
5)
True.
Ionization energy is defined as the amount of energy needed to "remove" and electron from a neutral atom
6)
True..
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.
