Question

Nitrogen shows different oxidation states ranging from:

• A. $-3$ to $+5$
• B. $-5$ to $+5$
• C. $0$ to $-5$
• D. $-3$ to $+3$

Answer 1

The correct option is A $-3$ to $+5$

Since nitrogen atom have 5 electrons in its outermost shell, so higher electronegative elements can extend its oxidation state up to +5, while in case of taking electrons it cannot go beyond 8 electrons. So at most it can accept 3 electrons.
