Question

Classify each of the following on the basis of their atomicity

(a) $F_2$ (b) $N{O}_2$ (c) $N_{2}O$
(d) $C_2{H}_6$ (e) $P_4$ (f) $H_2{O}_2$
(g) $P_4{O}_{10}$ (h) $O_3$ (i) $HCI$
(j) $C{H}_4$ (k) $He$ (l) $Ag$

Answer 1

Atomicity is defined as the number of atoms in the molecules of an element.
The atomicity of the following compounds are as follows
(a) 2 (b) 3 (c) 3 (d) 8 (e) 4 (f) 4 (g) 14 (h) 3 (i)2 (j) 5
(k) 1 (l) 1

Based on atomicity the compounds are classified as
(i) Monoatomic (consisting of one atom) - (k) $He$ , (l) $Ag$
(ii) Diatomic (consisting of two atoms) - (a) $F_2$ , (i) $HCI$
(iii) Polyatomic (consisting of more than two atoms) - (b) $N{O}_2$ , (c) $N_{2}O$ , (d) $C_2{H}_6$ , (e) $P_4$ , (f) $H_2{O}_2$ , (g) $P_4{O}_{10}$ , (h) $O_3$ , (j) $C{H}_4$
