Bonds Form When Energy is Gained: Na Cation

[LogicalAcid]

When energy is to be gained correct? It takes more energy to take a valence electron off Na than energy is gained when it is put on another atom to make a cation. I know the energy didn't just disappear, energy never does, what happened to the remaining energy that wasn't gained?

Do bonds only form when energy is to be gained?

If that is the case, why does it take more energy to take a valence electron off Na than energy is gained when it is attached to another atom to make a cation?

You are confusing something, you can't add electron to atom to make it a cation.

Ion,sorry.
