How to Write the Formula for Nitrogen trifluoride

In this video we'll write the correct formula for Nitrogen trifluoride (NF3). To write the formula for Nitrogen trifluoride we’ll use the Periodic Table and follow some simple rules.

When we have a non-metal and a non-metal we have a molecular compound (sometimes called covalent). Molecular compounds are some of the simplest to name.

Keys for Writing the Formulas for Molecular Compounds:

- Write the element symbol for both elements.
- Place a subscript after each element according to its prefix.

Note: Don’t write the subscript '1'.

---------
Prefixes
mono- 1
di- 2
tri- 3
tetra- 4
penta- 5
hexa- 6
hepta- 7
octa- 8
nona- 9
deca- 10
---------
Caution: We only write "mono" for the second element in a molecular compound. So CO would be carbon monoxide. Monocarbon monooxide is incorrect.
