(a) (i) Tendency to lose electrons decreases.
(ii) Increases.
(b) The three compounds are X(NO₃)₂, XSO₄ and X₃(PO₄)₂.
Valence electrons of element X is 2. Therefore, element X belongs to group 2. It will form ionic compounds because X loses 2 electrons to achieve the electronic configuration of inert gas and forms a positively,charged ion.
