The number of atoms of nitrogen represented in the formula NH4NO is :
- A
1
- B
2
- C
3
- D
4
The compound NH4NO consists of ammonium (NH4) and a nitrate (NO) group. The ammonium part contributes one nitrogen atom, and the nitrate part contributes another nitrogen atom. Thus, the total number of nitrogen atoms in NH4NO is two. Options A, C, and D are incorrect as they do not account for the correct number of nitrogen atoms in the compound.
Option A: This option suggests that there is only one atom of nitrogen in the formula NH4NO. However, this is incorrect because NH4NO actually contains two nitrogen atoms.
Option B: This is the correct answer. The compound NH4NO contains two nitrogen atoms: one from the NH4 (ammonium) and one from the NO (nitrate).
Option C: This option incorrectly suggests that there are three nitrogen atoms in the formula NH4NO. The correct count is two nitrogen atoms.
Option D: This option incorrectly suggests that there are four nitrogen atoms in the formula NH4NO. There are actually only two nitrogen atoms.
