NF₃

Explanation:

The formula of nitrogen fluoride will be NF₃: it would be called Nitrogen trifluoride.

          Nitrogen has 7 electrons with 5 valence electrons

          Fluorine has 9 electons with 7 valence electrons.

For atoms to combine, they use their combining powers which is a function of their valency:

       Valency of Nitrogen is usually +3

       Valency of fluorine here is -1

To form a bond;  

                                                       N                            F

  combining power                         3                            1

  Exchange of power                     1                              3

                     Formula of compound             NF₃

note: Nitrogen is less electronegative than fluorine.
