NEET Chemistry: Chemistry - Nitrogen questions with solutions

Q1. Nitrogen shows different oxidation states ranging from:

1. -3 to +5
2. -5 to +5
3. 0 to -5
4. -3 to +3

Answer: -3 to +5

Nitrogen can be as low as -3 in compounds like ammonia or nitrides, and as high as +5 in nitrate or nitric acid. So its oxidation states span from -3 to +5.
