In the isotope Cl-37, how many neutrons are present?

Explanation:
The number of neutrons is found by subtracting the atomic number (protons) from the mass number. Chlorine has 17 protons, and the isotope Cl-37 has a mass number of 37, so neutrons = 37 − 17 = 20. Therefore, there are twenty neutrons in Cl-37. Isotopes of chlorine differ in neutron count while keeping the same number of protons.
