Identify the hybridization of the n atom in nf3.

sp3 hybridization

Explanation:

Hello,

Based on the Lewis structure Nitrogen has 3 valence electrons with a lone pair of non-bonded electrons, thus, the hybridization calculation rule,

Allows us to identify that the has three attached atoms and one lone pair. Now, by considering the convention: sp3=4, sp2=3  and sp=2 , one finds that:

Therefore, has sp3 hybridization.

Best regards.
