WebThe third ionization energy is the energy required to form 3+ cations: M 2+ (g) ® M 3+ (g) + e- and so on. Ionization energies are always positive numbers, because energy must be supplied (an endothermic energy change) to separate electrons from atoms. WebThe general trend in ionisation energy across period 3 elements is that it increases with increasing nuclear charge. There are 2 "dips" in this trend, these are with the elements aluminium and sulfur. The 2 dips in the ionisation energies, one as we go from Mg to Al and the other as we go from the element P to S. sharp throbbing pain
