1.	An element X (2, 8, 2) combines separately with SO_(4)^(2-),PO_(4)^(3-) radicals. (i) Write the formulae of the two compounds so formed. (ii) To which group of the modern periodic table does the element X belong? (iii) Will it form covalent or ionic compound ? Give reasons.
Answer» Solution :(i) FORMULAE of these compounds are `XSO_(4),X_(3)(PO_(4))_(2)`. (ii) It belongs to group `2^(nd)AND3^(rd)` period. (iii) It will form ionic compounds as it can lose TWO electrons to acquire stable electronic configuration.
