* Valence Electrons of Nitrogen (N): Nitrogen is in group 15 (or VA) of the periodic table, so it has 5 valence electrons.
* Valence Electrons of Fluorine (F): Fluorine is in group 17 (or VIIA), so it has 7 valence electrons.
* Total Valence Electrons:
* Nitrogen contributes 5 electrons.
* Four fluorine atoms contribute 4 x 7 = 28 electrons.
* Total: 5 + 28 = 33 valence electrons
Therefore, NF4 has 33 valence electrons.
