Here's how to figure out the number of atoms in a butane molecule:

1. The Chemical Formula:

* Butane's chemical formula is C₄H₁₀

2. Counting the Atoms:

* Carbon (C): The subscript '4' next to 'C' indicates there are 4 carbon atoms.

* Hydrogen (H): The subscript '10' next to 'H' indicates there are 10 hydrogen atoms.

3. Total Atoms:

* 4 carbon atoms + 10 hydrogen atoms = 14 atoms

Therefore, there are 14 atoms in a butane molecule.
