Recall that a neutral atom has an equal number of protons and electrons.
Identify the atomic number of carbon from the periodic table, which represents the number of protons in the nucleus.
For carbon, the atomic number is 6, meaning it has 6 protons.
Since the atom is neutral, the number of electrons must also be 6 to balance the positive charge of the protons.
Therefore, the number of electrons in a neutral carbon atom is equal to its atomic number, which is 6.
