Heya.. Empress Here!!

• As we already know that the number of protons and electrons is equal.
• And number of electrons in Cl is 17 (as mentioned).

• And total mass of an atom = Number of Electrons + Number of Neutrons which is mentioned as 37.

• So according to the equation :- Number of Neutrons = 37 - Number of Electrons.

=> Number of Neutrons = 37-17 or 20.

• And as you've selected 20 in MCQ, you're totally correct!

• Felicitations
