Question

What is the valency of?
e) Nitrogen in the following compound
i) $N_2{O}_3$ ii) $N_2{O}_5$ iii) $N{O}_2$ iv)$NO$

Answer 1

• In $N_2{O}_5$, there are two nitrogen atoms and five oxygen atoms. As a result, it has a valency of 5.
• In $N_2{O}_3$, there are two nitrogen atoms and three oxygen atoms. As a result, it has a valency of 3.
• In $N{O}_2$, the charge of oxygen is -2 and the charge on the nitrogen is: x + 2(-2) = 0 x = +4
• Thus, nitrogen has a valency of 4. In NO, the charge of oxygen is -2 and the charge on the nitrogen is: x+(-2)=0 x=+2 Thus, nitrogen has a valency of 2
