Step 1: Identify the total number of valence electrons in the molecule
The Lewis structure for a molecule includes the nuclei and core electrons, as well as the valence electrons. Nitrogen (N) is in the 15th group of the periodic table, so it has 5 valence electrons. Fluorine (F) is in the 17th group, so it has 7 valence electrons. The molecule N^2F^2 has two nitrogen atoms and two fluorine atoms, so the total number of valence electrons is:
