WebDecrease across a period Proton number increases Effective nuclear charge increases Stronger attraction between nucleus and valence electron Thus, atomic radius decreases Increases down a group Energy level increases Shielding effect increases Weaker attraction between nucleus and valence electrons Thus, atomic radius increases. WebBeryllium's goes up to 900 kilojoules per mole, and then again, in general, we see this increase in ionization energies going over to neon. So, going across a period, there's an increase in the ionization energy. And that's because, as we go across our period, there's an increase in the effective nuclear charge. So, increase in Z effective.
