Question

Show that relative atomic weight of chlorine is 35.5

Answer 1

The answer to why chlorine has anatomic weight of 35.5 not 35 is because of something called isotopes. Isotopes are atoms with the same number of protons (in the case ofchlorine that means 17 protons) but different numbers of neutrons.Chlorine has two common isotopes,Chlorine-35 and Chlorine-37
