To determine the number of atoms in the formula (2 \text{Ca}_3(\text{PO}_4)_2), first break it down. The formula contains 2 calcium phosphate units. Each unit has 3 calcium (Ca) atoms, 2 phosphorus (P) atoms, and 8 oxygen (O) atoms (since (4) oxygen atoms are multiplied by (2)). Therefore, the total number of atoms is (2 \times (3 + 2 + 8) = 2 \times 13 = 26) atoms.
