1.	Magnesium is an element of group 2 of the periodic table. It forms compounds such as (i) magnesium oxide, MgO, (ii) magnesium hydroxide, Mg(OH)_2, (iii) magnesium sulphate, MgSO_4 and (iv) magnesium chloride, MgCl_2. Calcium is also an element of group 2. Write the formulae of calcium oxide, calcium hydroxide, calcium sulphate and calcium chloride.
Answer» SOLUTION :The ELEMENTS of the same group FORM compounds of similar formulae. Thus (i) Calcium oxide CaO, (ii) calcium HYDROXIDE, `Ca(OH)_2`, (iii) calcium sulphate, `CaSO_4`, (iv) calcium chloride, `CaCl_2`.
