How many neutrons are in 36Cl?

Answer 1

The way to work this out is this:

The 36 in 36CL relates to its Atomic Mass while the atomic number of CL is 17.

The atomic mass of an atom's isotope is directly proportional to the total number of protons and neutrons in its nucleus.

While the the atomic number of an atom/element is directly proportional to the number of protons in the nucleus.

Therefore if you subtract the atomic number from the atomic mass you end up with the number of neutrons in the nucleus.

In this case 36-17=19

So there are 19 neutrons in 36CL

Answer 2

The nucleus of chlorine-36 (36Cl) contains 20 neutrons. This is calculated by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons). In the case of chlorine, the atomic number is 17, so the number of neutrons is 36 - 17 = 19.
