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 the valence shell of X(g), then which reaction, reaction (i) or reaction (ii), would have more negative number for energy change? Why? What is this energy change called?
