does anyone know what the difference between 35Cl and 37Cl is?

They are isotopes of Chlorine. Cl-35 means that this isotope has a total of 35 protons and neutrons. But since the atomic number (number of protons) of Chlorine is 17 or 17 protons, then by subtraction the number of neutrons is 18.
On the other hand, the isotope Cl-37 means that it has a total of 37 protons and neutrons. This means it has 17 protons and 20 neutrons.
Also, based on these differences, this means that Cl-37 will weigh heavier than Cl-35. However, Cl-35 occcurs in greater abundance than that of Cl-37. The atomic weight listed in the periodic table is actually the average of the weight of the different isotopes based on their percentage abundances.

They are different isotopes, the difference is in the number of neutrons.
the latter has two more neutrons than 35Cl
