Question

Whats the difference between two atoms of carbon having the same number of neutrons?

Answer 1

Answer: Both atoms are carbon, so the number of protons is the same

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties.
