Atomic Number – Protons, Electrons and Neutrons in Carbon. Carbon is a chemical element with atomic number 6 which means there are 6 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
