Solution
The correct answer is "17 protons, 20 neutrons".
Here's why:
The atomic number of an element, which is the number of protons in the nucleus of an atom, identifies the element. For Chlorine (Cl), the atomic number is 17, which means it has 17 protons.
The mass number (in this case, 37) is the total number of protons and neutrons in the nucleus. If we subtract the number of protons (17) from the mass number (37), we get the number of neutrons. So, 37 - 17 = 20 neutrons.
So, Cl-37 has 17 protons and 20 neutrons.
