MCQ
Nitrogen show different oxidation states in the range
  • A
    $0$ to $+5$
  • ✓
    $-3$ to $+ 5$
  • C
    $-5$ to $+ 3$
  • D
    $-3$ to $+ 3$
✓

Answer

Correct option: B.
$-3$ to $+ 5$
b
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.
