(A)similar ionisation enthalpy
(B)similar metallic character
(C)similar ionic size and charge/radius ratioCorrect
(D)similar electronegativity

Answer: (C)

Solution

The diagonal relationship arises because and have similar polarising power, i.e. similar charge/radius ratio (ionic potential), since the increase in charge from
