1. The problem statement, all variables and given/known data
Using data from text determine the following values:
a. Electron Affinity of Mg+2
b. Ionization energy of Cl(-1)
c. Electron affinity of Cl(+1)
d. Ionization energy of Mg(-1)

2. Relevant equations

3. The attempt at a solution
I'm assuming that you can't find actual values and my book (Zumdahl 7e) doesn't state them but I kind of made generalizations.

a. I said less than 230 KJ/mole since it is a positive ion and thus it would be easier to add electrons and it possibly will release energy
b. Less than 1251.1 kJ/mole because there is more sheilding and thus easier to remove an electron
c. less than -349 kJ/mole because it would be easier to add electrons since its positive, thus more energy will be released
d. Less than 737.7 kJ/mole because there are more electrons and thus it is easier to remove one

Is my thought process correct?
