The chemical formula NH4Cl represents ammonium chloride. To express the answers numerically, we need to determine the number of atoms for each element in the formula.

Let's break down the formula into its elements:

NH4Cl has two elements:
1. NH4 - represents ammonium (NH4^+) ion.
2. Cl - represents chloride (Cl^-) ion.

Let's determine the number of atoms for each element:
1. Ammonium (NH4^+): The formula NH4 indicates that there is 1 nitrogen atom (N) and 4 hydrogen atoms (H). So, in total, there is one nitrogen atom and four hydrogen atoms.
N: 1 atom
H: 4 atoms

2. Chloride (Cl^-): The formula Cl indicates that there is 1 chlorine atom (Cl).
Cl: 1 atom

Therefore, the number of atoms for each element is:
N: 1 atom
H: 4 atoms
Cl: 1 atom

To express the answers numerically, we write: 1, 4, 1.
