To determine the number of atoms of each element in the chemical formula [tex]\( \text{P}_2\text{O}_5 \)[/tex]:
1. Identify the elements present:
- The formula [tex]\( \text{P}_2\text{O}_5 \)[/tex] consists of two types of atoms: Phosphorus (P) and Oxygen (O).
2. Determine the number of each atom as indicated by the subscript in the formula:
- The subscript next to P (Phosphorus) is 2, which indicates there are 2 atoms of Phosphorus.
- The subscript next to O (Oxygen) is 5, which indicates there are 5 atoms of Oxygen.
Therefore, in the chemical formula [tex]\( \text{P}_2\text{O}_5 \)[/tex], there are:
- 2 atoms of Phosphorus,
- 5 atoms of Oxygen.
Comparing these results with the given options:
1. [tex]\( \text{2 phosphorus and 5 oxygen} \)[/tex]
2. [tex]\( \text{5 phosphorus and 2 oxygen} \)[/tex]
3. [tex]\( \text{1 phosphorus and 5 oxygen} \)[/tex]
4. [tex]\( \text{2 phosphorus and 1 oxygen} \)[/tex]
The correct answer is:
- 2 phosphorus and 5 oxygen
