Solution: Write the formula for each molecular compound.phosphorus pentafluoride

Solution: Write the formula for each molecular compound.phosphorus pentafluoride


Write the formula for each molecular compound.

phosphorus pentafluoride


We’re being asked to write a chemical formula for phosphorus pentafluoride.


A covalent or molecular compound is composed of more than one nonmetal together.

Rules for naming molecular compounds:

1. The first nonmetal is named normally and uses numerical prefixes except mono.
2. The second nonmetal keeps its base name but has its ending changed to -ide.

Numerical Prefixes:

Mono              1                     Di                    2
Tri                   3                     Tetra               4
Penta             5                      Hexa              6
Hepta             7                      Octa               8
Nona              9                      Deca              10

*numbers are written as subscripts of the element in the chemical formula
