Chemistry what is a nuclide?

Self-tutoring about chemistry: the tutor mentions nuclide.

A nuclide is more specific than an atom – it’s closer to the idea of an isotope.

An atom is identified by its number of protons, aka its atomic number. Yet, the type of atom doesn’t specify its number of neutrons; hence, ₆¹²C and ₆¹⁴C are both carbon atoms, even though one has six protons while the other has eight. (The top number, 12 or 14, is the mass, which is the sum of protons and neutrons; the bottom number, 6 in both cases, is the number of protons: carbon, by definition, always has 6 protons. Therefore, ₆¹²C has 6 neutrons, while ₆¹⁴C has 8.)

Therefore, ₆¹²C is one nuclide, while ₆¹⁴C is another. That’s how I understand the term nuclide, anyway:)
