Step 1: Recognize the components of a chemical formula
A chemical formula represents the elements in a compound and the number of atoms of each element. In the case of diphosphorus pentaoxide, the name suggests that it contains two phosphorus atoms (diphosphorus) and five oxygen atoms (pentaoxide).
Step 2: Identify the correct chemical formula for diphosphorus pentaoxide
The correct chemical formula for a compound with two phosphorus atoms and five oxygen atoms is P^4O^10, not P^2O^5. This is because phosphorus exists in group 15 of the periodic table, which means it typically forms compounds with a + 5 oxidation state. Therefore, the correct formula for diphosphorus pentaoxide is actually P^4(OH)10, which upon dehydration forms P^4O^10.
Final Answer
It is incorrect to name the chemical compound P^2O^5 as diphosphorus pentaoxide because the formula P^2O^5 actually represents diphosphorus pentoxide, where phosphorus has a + 5 oxidation state. The correct formula for diphosphorus pentaoxide should be P^4O^10, where phosphorus has a + 5 oxidation state and there are four phosphorus atoms in the formula.
