1 : one of two or more compounds, radicals, or ions that contain the same number of atoms of the same elements but differ in structural arrangement and properties2 : a nuclide isomeric with one or more others
If an element has one and only one stable isotope, an example is Gold.
For example a thorium isotope is Th-231 or 23190 Th.
An example of an isotope in my house would be carbon-14, which is used in carbon dating to determine the age of organic materials.
An example with a zinc isotope: 81Zn (mass number as superscript before the chemical symbol)
Each isotope, stable or unstable, has a specific symbol; for example K-40 for potassium 40.
Sodium chloride is a compound, not an isotope.

An example of an atom is carbon (C), which has six protons. An example of an ion is a chloride ion (Cl-), which has gained an electron. An example of an isotope is carbon-14 (14C), which has 8 neutrons instead of the usual 6.
Ionized hydrogen-1 isotope is identical to a proton.
The parent isotope is the original radioactive isotope that undergoes decay to form the daughter isotope. The daughter isotope is the stable isotope that is formed as a result of the radioactive decay of the parent isotope.
