Select the chemical species in which the nitrogen atom has a negative oxidation number. The sum of their oxidation numbers (with sign) will be: NH₄Cl , NaNO₃ , NOF₃ , NO₂⁻, NH₂OH , NH₂F

TestHub · Accepted Answer

To find the sum of oxidation numbers for nitrogen in species where it is negative:

1. NH₄Cl: N = -3

2. NaNO₃: N = +5

3. NOF₃: N = +5

4. NO₂⁻: N = +3

5. NH₂OH: N = -1

6. NH₂F: N = -1

Negative oxidation numbers are -3, -1, -1.

Sum = $(- 3) + (- 1) + (- 1) = - 5$ .
