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.
WebHelium has 2 protons per atom which is also a molecule. The atomic number of He is 2 which places He at the top of the Noble gas group 8A.
