P2O5 is the empirical formula for the polymorph of P4O10. It is called phosphorous pentoxide under IUPAC naming conventions, but also known as phosphoric anhydride and diphosphorous pentoxide.
molecules
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
I do think that they are molecules.
Phosphorus pentoxide or phosphorus(V) oxide.
P2O5 is the empirical formula for phosphorus(V) oxide, P4O10.
molecules
The structural formula of P2O5 is O=P(O)OP(=O)O, where the central phosphorus atom is bonded to four oxygen atoms through double bonds. The molecule has a cage-like structure with a central P-O-P bridge.
Covalent compounds
Two or more atoms of different elements joined together form a compound. If it is a metal and non-metal (for example sodium and chlorine), they are ionically bonded. If it is two non-metals (for example methane is carbon and hydrogen), they are covalently bonded.
Diphosphorus Pentoxide is the name of the formula P2O5.
I do think that they are molecules.
The correct name for P2O5 is diphosphorus pentoxide. This compound is composed of two phosphorus atoms and five oxygen atoms. The prefix "di-" indicates the presence of two phosphorus atoms, while the suffix "-pentoxide" indicates the presence of five oxygen atoms.
Phosphorus pentoxide or phosphorus(V) oxide.
An atom is a piece of an element. A molecule is a number of pieces of one or more elments joined together. So H2O must be a molecule.
P2O5 is the empirical formula for phosphorus(V) oxide, P4O10.
