Solution
The correct answer is "17 protons, 20 neutrons".
Here's the step-by-step explanation:
-
The atomic number of an element, which is the number of protons, is represented by the symbol of the element. In this case, Cl stands for Chlorine, which has an atomic number of 17. Therefore, Chlorine has 17 protons.
-
The number after the hyphen (37 in Cl-37) represents the atomic mass number, which is the sum of protons and neutrons.
-
To find the number of neutrons, you subtract the number of protons from the atomic mass number. So, 37 (atomic mass number) - 17 (number of protons) = 20 neutrons.
So, Cl-37 has 17 protons and 20 neutrons.
