a) $N{a}^{+},H_3{O}^{+},NH{{}_4}^{+}$
b) $CO{{}_3}^{2-},NO{{}_3}^{-},HCO{{}_3}^{-}$
c) $P^{3-},HCl,C_2{H}_6,P{H}_3$
d) $N^{3-},O^{2-},F$

• A. a, b, d
• B. b, c, d
• C. a, b, c, d
• D. a, b, c

Answer 1

The correct option is D a, b, c

a) $N{a}^{+},H_3{O}^{+},NH{{}_4}^{+}$ contains 10 electrons each.

b) $CO{{}_3}^{2-},NO{{}_3}^{-},HCO{{}_3}^{-}$ contains 32 electrons each

c) $P^{3-},HCl,C_2{H}_6,P{H}_3$ contains 18 electrons each.

d) $N^{3-},O^{2-},F$ contains 10, 10 and 9 electrons respectively.
