WebLithium is a chemical element with atomic number 3 which means there are 3 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. Web10 jan. 2024 · Well, it is a carbon nucleus by specification. ALL carbon nuclei contain 6 protons, 6 positively charged, massive nuclear particles; i.e. Z, the atomic number = 6. This what defines the atom as carbon. But here the nucleus also contains 8 neutrons, 8 neutrally charged, massive nuclear particles.
