To find the number of neutrons in an atom you can use and equation

N = Mass no. - Protons 

N of chlorine-36 = 36 - 17 = 19 

so chlorine-36 has 19 neutrons 

hope that helps  

17 protons and 19 neutrons. isotopes of the same element have the same number of protons but a different number of neutrons
