Recall that a neutral atom has an equal number of protons and electrons.
Identify the atomic number of carbon, which represents the number of protons in the nucleus of a carbon atom.
Since carbon's atomic number is 6, it has 6 protons.
Because the atom is neutral, the number of electrons must also be 6 to balance the positive charge of the protons.
Therefore, the electron cloud of a neutral carbon atom contains 6 electrons.
