SUMMARY
The formation of a cation is an endothermic process, requiring energy input to overcome the ionization energy necessary to remove an electron from an atom. For instance, the potassium cation (K+) is smaller than the neutral potassium atom (K), yet this size reduction does not correlate with the energy dynamics of the ionization process. The energy absorbed during ionization is essential for the transition from a neutral atom to a positively charged cation, confirming that size change does not influence the heat of the reaction.
