검증된 단계별 안내1
Recall that the number of valence electrons corresponds to the electrons in the outermost shell of an atom in its ground state.
Identify the group number of each element in the periodic table, as elements in the same group have the same number of valence electrons.
Carbon (C) is in group 14, so it has 4 valence electrons.
Oxygen (O) is in group 16, so it has 6 valence electrons.
Fluorine (F) is in group 17 with 7 valence electrons, and Nitrogen (N) is in group 15 with 5 valence electrons.
