Question

The element which, forms oxides in all oxidation states varying from +1 to +5 is:

• A. $N$
• B. $P$
• C. $As$
• D. $Sb$

Answer 1

The correct option is A $N$

Nitrogen atom can form oxides in all oxidation states varying from +1 to +5.

$N_{2}O$ Nitrogen oxidation state is +1

$NO$ Nitrogen oxidation state is +2

$N_2{O}_3$ Nitrogen oxidation state is +3

$N{O}_2$ Nitrogen oxidation state is +4

$N_2{O}_5$ Nitrogen oxidation state is +5.

So answer is A.
