Is diphosphorus pentoxide an ionic or a molecular compound?

A. Ionic
B. Molecular
I say B

true

To determine whether diphosphorus pentoxide (P2O5) is an ionic or a molecular compound, we need to consider the types of elements present and how they are bonded.

In diphosphorus pentoxide, we have two nonmetals - phosphorus (P) and oxygen (O) - which suggests that it is a molecular compound. Molecular compounds consist of covalent bonds formed by the sharing of electrons between nonmetal atoms.

Additionally, the naming convention of diphosphorus pentoxide, where the "di-" prefix indicates the presence of two phosphorus atoms, further supports the molecular nature of the compound.

Hence, your answer of B. Molecular is correct.

Diphosphorus pentoxide (P2O5) is a molecular compound.
