Classify each of the following on the basis of their atomicity.
(a) F2
(b) NO2
(c) N2O
(d) C2H6
(e) P4
(f) H2O2
(g) P4O10
(H) O3
(i) HCl
(j) CH4
(k) He
(l) Ag
Ans. (a) 2 atom
(b) 3 atom
(c) 3 atom
(d) 8 atom
(e) 4 atom
(f) 4 atom
(g) 14 atom
(h) 3 atom
(i) 2 atom
(j) 5 atom
(k) 1 atom (noble gases are always monoatomic)
(l) Polyatomic (because metals are bound by metallic bond and any measurable quantity
of a metal can contain millions of atoms.)
