Recall that the number of electrons in a neutral atom is equal to its atomic number, which is the number of protons in the nucleus.
Identify the atomic numbers of the given elements: Oxygen (O), Neon (Ne), Fluorine (F), and Nitrogen (N).
Oxygen has an atomic number of 8, meaning it has 8 protons and, since it is neutral, 8 electrons.
Neon has an atomic number of 10, Fluorine has 9, and Nitrogen has 7, so none of these have exactly 8 electrons.
Therefore, the neutral element with 8 electrons is the one with atomic number 8, which is Oxygen (O).
