Solution

The correct option is D
(d) (i) 3 and 7 - Electrovalent
(ii) 6 and 9 - Covalent
(iii) 11 and 16 - Electrovalent
(iv) 14 and 12 - Covalent

(i) 3 and 7 - Electrovalent - electrons in the valence shell are transferred from one atom to the other
(ii) 6 and 9 - Covalent - electrons are shared between two atoms
(iii) 11 and 16 - Electrovalent - electrons in the valence shell are transferred from one atom to the other
(iv) 14 and 12 - Covalent - electrons are shared between two atoms
