Verified step by step guidance1
Recall that the number of protons in the nucleus of an atom is called the atomic number, which uniquely identifies each element.
Look up the atomic numbers of the given elements: Nitrogen (N), Oxygen (O), Fluorine (F), and Carbon (C).
Nitrogen has an atomic number of 7, meaning it has 7 protons.
Oxygen has an atomic number of 8, meaning it has 8 protons.
Fluorine has an atomic number of 9, and Carbon has an atomic number of 6, so neither has 8 protons.
