when you add the electron to Calcium the energy required is 494
where is that number found?
what constitutes as required a cation needing to push an electron or is that released because of the electron leaves?

Re: Ionic Bond formation
That energy is required to overcome the effective nuclear charge that is acting on the electron.

Re: Ionic Bond formation
if the energy required is 494 would we be expected to find this number or is the number given? I have no idea how to find that number

it should be given, but I believe we just need to know the topic and be able to use any information given, not to memorize.
Re: Ionic Bond formation
If you are referring to the ionization energy of Na, this energy must be added to the atom to separate the electron from the rest of the atom:
Na + 494 kJ/mol --> Na+ + e-
The ionization energy is usually measured experimentally.
