How and when does an ionic radius increase? - Quora

WebApr 13, 2014 · An ion's size, compared to its parent atom, depends on whether it gains or loses electrons. Gaining electrons increases the apparent diameter, while losing electrons makes the ion smaller than the neutral atom. For example if Na loses one electron to form N a+, the latter is smaller than the Na atom. When O gains two electrons to form O2− the ... 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.
