Answer

Since there are three electrons more than the noble gas configuration in the atom so the atom will try to lose three electron to gain noble gas configuration. Therefore, it will form a cation X3+.

Formula of its:

(i) Sulphate — X2(SO4)3

(ii) Nitrate — X(NO3)3

(iii) Phosphate — XPO4

(iv) Carbonate — X2(CO3)3

(v) Hydroxide — X(OH)3
