To determine the number of oxygen atoms in the chemical formula Mg3(PO4)2, we can break down the formula as follows:

1. The formula contains the phosphate (PO4) group.
2. Each phosphate group (PO4) has 4 oxygen atoms.
3. There are 2 phosphate groups in the formula (indicated by the subscript 2).

So, the total number of oxygen atoms is calculated as follows:

Number of oxygen atoms = 4 oxygen atoms/group × 2 groups = 8 oxygen atoms.

Thus, the answer is:

**8**
