Answer
Answer:
A. 2 phosphorus and 5 oxygen
Explanation:
Step1: Identify sub - script meaning
In a chemical formula, sub - scripts indicate atom numbers.
Step2: Analyze phosphorus atoms
For $P_2O_5$, the sub - script of P is 2, so 2 phosphorus atoms.
Step3: Analyze oxygen atoms
The sub - script of O is 5, so 5 oxygen atoms.
