Ionic radii of ca2+
WebSolution. The correct option is C P 3− > S2− > Cl− > K+ > Ca2+. For isoelectronic species, as nuclear charge increases radius decreases. Greater the positive charge, lesser the size of ion. Greater the negative charge, larger the size of ion. ∴ P 3− >S2− >Cl− >K+ >Ca2+. Suggest Corrections. Web15 feb. 2015 · 0. Mg is smaller the Ca because it is above it in the periodic table, magnesium being a period above it shows that it has one less electron shell so it's smaller, calcium …
