Arrange the following in the order of their increasing effective nuclear charge, increasing ionization potential and increasing size. Give appropriate reasons to support your arrangement. (X is an element) X, X−, X2−, X+, X2+ You have two reactions associated with the elements X and Y: X(g) + e → X−(g)…..(i) Y(g) + e → Y−(g)…..(ii) A certain amount of energy is released in both reactions. If addition of an electron to the valence shell of Y(g) was easier than to...
