Question

CHM 10331 Exan 2 (12 point) Fill in the following table giving the symbol, atomic number, mass number, number of neutrons, electrons, and protons in each case: 1. Atomic Electrons Number Mass number Neutrons Electrs Protons Ca 41 12 13 Cu 34 (6 points) For each of the following elements, give the symbol, indicate whether it is a metal or nonmetal, and predict whether it is shiny or dull. 2. Symbol (l pt.) Metal or Nonmetal (1 pt.) Shiny or Dull (1 pt.) Element Copper Oxygen Iron Fluorine 3. (6 pts) Balance the following equations. a) Fe2O3 + C b) P+0

Explanation / Answer

1.

Note: The no. of electrons in Mg = 12

And the no. of electrons in Cu = 29

I hope there were some typo errors in the given table.

Symbol Atomic number Mass number Neutrons Electrons Protons Ca 20 41 41-20 = 21 20 20 Mg 12 24 24-12 = 12 13 12 Cu 29 64 64-29 = 35 34 29
