* Al2(CO3)3: This is the chemical formula for aluminum carbonate.

* Al: Represents one aluminum atom.

* C: Represents one carbon atom.

* O: Represents one oxygen atom.

Breakdown:

* Al2: There are 2 aluminum atoms.

* (CO3)3: The parentheses mean the entire CO3 group appears 3 times.

* C: There are 3 carbon atoms (1 carbon atom per CO3 group x 3 groups).

* O: There are 9 oxygen atoms (3 oxygen atoms per CO3 group x 3 groups).

Total:

* 2 aluminum atoms + 3 carbon atoms + 9 oxygen atoms = 14 atoms

Therefore, there are 14 atoms in one molecule of Al2(CO3)3.
