# How many neutrons does chlorine atom have?

Not all atoms of an element, therefore, have the same atomic mass number. All chlorine atoms, for instance, have 17 protons. However, some chlorine atoms have 18 neutrons, while other chlorine atoms have 20 neutrons. Atoms of chlorine with 18 and 20 neutrons are called chlorine isotopes.

### Can you tell from the periodic table exactly how many neutrons are in an atom?

Because we can find the number of protons and the atomic mass of an atom by looking at its element information in the periodic table, we can calculate the number of neutrons in that atom by subtracting the number of protons from the atomic mass.
