WebPotassium is a chemical element with atomic number 19 which means there are 19 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. WebWe use Lewis symbols to describe valence electron configurations of atoms and monatomic ions.
