Here's how to figure out the number of atoms in ammonium chloride (NH₄Cl):

* Ammonium ion (NH₄⁺):

* 1 Nitrogen atom (N)

* 4 Hydrogen atoms (H)

* Chloride ion (Cl⁻):

* 1 Chlorine atom (Cl)

Total atoms: 1 + 4 + 1 = 6 atoms

Therefore, there are 6 atoms in one molecule of ammonium chloride (NH₄Cl).
