To determine the number of atoms of each element in the chemical formula [tex]\( \text{P}_2\text{O}_5 \)[/tex], let's break down the formula step-by-step:
1. Identify the elements and their subscripts:
- The formula [tex]\( \text{P}_2\text{O}_5 \)[/tex] consists of phosphorus (P) and oxygen (O).
- The subscript next to P (which is 2) indicates the number of phosphorus atoms.
- The subscript next to O (which is 5) indicates the number of oxygen atoms.
2. Interpret the subscripts:
- The subscript 2 next to phosphorus means there are 2 atoms of phosphorus in the molecule.
- The subscript 5 next to oxygen means there are 5 atoms of oxygen in the molecule.
Therefore, the breakdown of the chemical formula [tex]\( \text{P}_2\text{O}_5 \)[/tex] provides us with:
- 2 atoms of phosphorus,
- and 5 atoms of oxygen.
Based on this detailed analysis, the correct answer is:
- 2 phosphorus and 5 oxygen.
