How many neutrons are found in the nucleus of one atom of chlorine-37?

Answer 1

#20#

the #-37# after the name chlorine shows the number of nucleons - the protons and neutrons found in the nucleus.

the proton number shows the number of protons in the atom. this is found at the bottom-left of the element symbol in the Periodic Table. for chlorine, this is #17#.

therefore, the number of neutrons in an atom of chlorine can be found by subtracting the proton number of chlorine from the mass number of chlorine.

#37 - 17 = 20#

there are #20# neutrons, #17# protons and therefore #37# nucleons in one atom of chlorine#-37#.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
