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 mei 2024 · All helium atoms have 2 protons. Isotopes occur when atoms of the same element have different masses. Since the number of protons of an element doesn't change, the difference in mass occurs because of different numbers of neutrons. Copper, for example, has two isotopes, copper-63 and copper-65. Copper-63 has 29 protons and a …
