Explanation:

Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons . The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.

example:chlorine is an example of an isotope it has a proton number of 17 and a mass number of 35 in some cases they have a proton number of 17 and a mass number of 37 there is difference in the number of neutron to calculate this we do it this way.for the first one

mass number=proton+neutron

neutron=mass number-proton

neutron=35-17

neutron=18

for the second one

neutron=37-17

neutron=20
