- Number: 46 or 23 pairs

- Location: In the nucleus

- Charge: Positive; equal and opposite to the total electron charge

- Mass: Almost all mass of atom

Neutrons

- Number: Varies by isotope; carbon generally has 6

- Location: Also in the nucleus

- Charge: Neutral

- Mass: Very slightly greater than the mass of a proton

Electrons

- Number: Equal to number of protons, thus always equal to 6

- Location: Orbiting the nucleus at set distances in a number of fixed shells

- Charge: Negative; always equal and opposite to the positive charge of its protons but with a much smaller magnitude

- Mass: Practically unnoticeable; 1/1836 times the mass of a proton
