To determine how many atoms of oxygen exist in the products of the reaction \( \text{Al} + \text{O}_2 \rightarrow \text{Al}_2\text{O}_3 \), we first need to look at the product, which is aluminum oxide (\( \text{Al}_2\text{O}_3 \)).
In \( \text{Al}_2\text{O}_3 \):
- There are 3 oxygen atoms.
Therefore, in the products of this reaction, there are **3 atoms of oxygen**. The correct answer is:
**3**
In \( \text{Al}_2\text{O}_3 \):
- There are 3 oxygen atoms.
Therefore, in the products of this reaction, there are **3 atoms of oxygen**. The correct answer is:
**3**
