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.

Chlorine is an element of atomic number 17. It is a mixture of two isotopes having mass number of 35 and 37. State the number of protons, electrons and neutrons in the following isotopes: Cl 35 17, Cl 37 17.
Neutral chlorine atom on left has 17 protons and 17 electrons. Sodium ion on right has 17 protons and 18 electrons, with a -1 overall charge. The names for positive and negative ions are pronounced CAT-eye-ons and ANN-eye-ons, respectively.
3 Σεπ 2019 · The number of protons and electrons in an atom or molecule determines its charge and whether it is a neutral species or an ion. This worked chemistry problem demonstrates how to determine the number of protons and electrons in an ion.
17 Απρ 2023 · On the left, the chlorine atom has 17 electrons. On the right, the chloride ion has 18 electrons and has a 1− charge. If we want to summarize the process of chlorine gaining an electron to form the ion, we may write it like this: Cl +e– →Cl– (4.9.2) (4.9.2) C l + e – → C l –.
