Understand the prefix 'tri-' means three, indicating there are three fluorine atoms.
Recognize that 'nitrogen trifluoride' means one nitrogen atom combined with three fluorine atoms.
Write the chemical formula by placing the symbol for nitrogen first (N), followed by the symbol for fluorine (F) with the subscript 3 to indicate three fluorine atoms: \(N F_3\).
Confirm that the formula \(N F_3\) correctly represents nitrogen trifluoride, matching the naming convention for molecular compounds.
