Chlorine is a chemical element with atomic number 17 which means there are 17 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.
From the periodic table, we find that it has 29 protons. The mass number (65) is the sum of the number of protons and neutrons. Therefore, we can subtract the number of protons from the atomic number to get the number of neutrons: # n = A – Z = 65 – 29 = 36.

22 Αυγ 2024 · One is the nucleus and the other is the orbit. Experiments by various scientists have shown that the nucleus of an atom contains protons and neutrons. The only exception is hydrogen, which has only protons in its nucleus but no neutrons. Electrons revolve around the nucleus in a specific orbit.
