WebProbably an element in the bottom left corner of the periodic table, like Francium. The first ionization energy is the energy required for an element to lose one of its electrons. Elements found in the first group (Li, Na, K, ...) all have one electron in their outer shell, so they would quite favorably lose that electron. Weban increase in atomic size because of additional repulsions between electrons, a decrease in size because of the additional protons in the nucleus, no effect at all as the two opposing tendencies of electron repulsion and nuclear attraction balance each other out.
