The ionization energy ‒ amount of energy required to remove the most loosely bound electron, the valence electron, of an isolated gaseous atom to form a cation. K + energy = K^+ + e^‒ Metals usually have 1‒3 valence electrons (1 valence electron in case potassium) and their ionization energy very low. Bromine have greater than potassium ionization energy Answer: Bromine
