Any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights.
Carbon-12 isotope is used to define the atomic mass unit, which is equal to 1/12th of the mass of a carbon-12 atom.
It is the neutron that makes changes in atomic nuclei to change them from one isotope to another. For any given element, that element will have a fixed number of protons. It is, after all, the number of protons that determine the elemental identity. But the number of neutrons in a given element can vary, and we use the term isotope to talk about which particular atom we're investigating. That is, we apply the term isotope to speak to an atom of a given element with a certain number of neutrons in its nucleus.
The term niche is used to define the role an organism plays within a community.

The word substance is used in chemistry to describe elements or compounds. It is used because when dealing with an unknown substance, it is important to not assign either name to it.
Isotopes are atoms of the same element that have different numbers of neutrons. Different isotopes of an element have the same atomic number, but different mass numbers. I hope I helped! ^_^

Carbon-12 isotope is used to define the atomic mass unit, which is equal to 1/12th of the mass of a carbon-12 atom.
