... This does not mean that there are 17 protons, 17 electrons and 18.5 neutrons in an atom of chlorine. It is not possible to have a fraction of a neutron, there can only be a whole number of neutrons in an atom. So what does it mean, and where does the 0.5 come from? Here is the explanation. The non i ...
