The chemical formula NH4NO3 represents ammonium nitrate. To determine the number of atoms of each element in the formula, we can break it down:
- NH4 indicates there are 1 nitrogen (N) atom and 4 hydrogen (H) atoms.
- NO3 indicates there is 1 nitrogen (N) atom and 3 oxygen (O) atoms.
Now, we can count the total number of each type of atom in the entire formula:
- Nitrogen (N): 1 (from NH4) + 1 (from NO3) = 2 nitrogen atoms
- Hydrogen (H): 4 (from NH4) = 4 hydrogen atoms
- Oxygen (O): 3 (from NO3) = 3 oxygen atoms
Putting this together, we have:
- 2 nitrogen
- 4 hydrogen
- 3 oxygen
Therefore, the correct answer is 2 nitrogen, 4 hydrogen, and 3 oxygen.
