First and second ionization energy?

Question

Which one of those two do you think is going to be higher (in terms of energy) and why?

Answer 1

in general the 2nd ionization energy is higher because it is harder to pull off a second electron and make the whole atom more positive. There are certain instances though when that isnt true. It is very hard to pull off the first electron off a halogen while pulling the second one off puts the atom into half p shell stability and thus it can be easier to pull of that second atom. Easier means less energy

Answer 2

It takes more energy to add or take away a second electron.
