Recall that a neutral atom has an equal number of protons and electrons.
Identify the atomic number of carbon, which is 6. The atomic number represents the number of protons in the nucleus of the atom.
Since the atom is neutral, the number of electrons must be equal to the number of protons to balance the positive charge.
Therefore, the total number of electrons in a neutral carbon atom is equal to its atomic number, which is 6.
No further calculation is needed; the answer is simply the atomic number of carbon.
