a potassium cation is smaller than potassium atom , doesn't that mea that heat is released ? lower enery atom(cation)

is that the reason that we put energy to ionize the atom? (heat absorbed endo thermic)

Size change has no correlation with the reaction heat.

Do you know what ionization energy is?
