(a) Predict the formula of the binary compound formed by the combination of the following pairs of elements:(i) Magnesium and nitrogen,(ii) Silicon and Oxygen.(b) Write the outer electronic configuration of d-block elements.

Answer»

(a) (i) Mg is group 2 element with a valence of 2; N belongs to group 15 with a valence of 3. So, the formula of the compound formed would be Mg3N2.

(ii) Si is group 14 element with a valence of 4; O belongs to group 16 with a valence of 2. So, the formula of the compound formed would be SiO2.

(b) (n-1) d1-10 , ns0-2
