Molecular. If you compare the electronegativities of phosphorus and chlorine, the difference between them falls in a spectrum of molecular compounds.
The quick and easy answers :
1) non metals only = molecular.
2) the prefixes in the name (tri =3, penta=5) are used for the naming of molecular compounds (and hydrates)
The name for the molecular compound PCl5 is phosphorus pentachloride.
Phosphorus pentachloride is a covalent compound.
BO is a molecular compound because it is composed of nonmetals (boron and oxygen) and forms covalent bonds.
Cr is a transition metal element, specifically chromium. It is not considered ionic or molecular on its own.
H2O is a molecular compound.
The name for the molecular compound PCl5 is phosphorus pentachloride.
Phosphorus pentachloride is a covalent compound.
Phosphorus pentachloride.
Phosphorus pentachloride has covalent bonding. It forms covalent bonds by sharing electrons between phosphorus and chlorine atoms.

the molecular shape is; As is in the middle, where the 5 chlorine are surrounding it. this gives a complete orbit for As, but you need to place 6 dots on each chlorine to complete their orbit as well. the name of it is, arsenic pentachloride.
