could you explain this thanks.

Since chlorine's atomic number is 17, this means that there are 17 protons in the nucleus. Subtract 17 from 37 and you get 20-- there are 20 neutrons in the nucleus of a chlorine-37 atom. Hope this helped!

There are 20 neutrons. Chlorine's atomic number is 17. That means there are 17 protons. Since Cl-37 has an atomic mass of 37, and am= atomic number + # of neutrons, 37-17=20.

The 37 refers to the total number of protons and neutrons in the nucleus. Chlorine has atomic number 17, which means 17 protons, so the number of neutrons must be 20.

The atomic number of chlorine is 17. Subtract that from 37, and you get 20, the total number of neutrons. Why, because this particular atom has gone through atomic decay, thus, losing protons in it's evolution. A natural process that all atoms go through.

37 - 17 (the proton number) = 20 neutrons

subtract the atomic number from atomic mass., then round to a whole number.
an-am= # of nuetrons
