If asked "What is an isotope ?" in GCSE Chemistry, a more detailed answer is required using one of the definitions below:Definitions of an isotope: Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. Another way to say the same ...
An isotope is a variant on an element that has a different atomic weight from other variants. Except for the commonest form of hydrogen— which has only a proton— every atomic nucleus in normal matter is made of both protons and neutrons. Isotopes of a given element have the same number...
Isotope and nuclide are closely related terms. When one speaks of isotopes, they are referring to the set of nuclides that have the same number of protons. Nuclide is a more general term, referring to a nuclear species that may or may not be isotopes of a single element. Examples: ...

However, isotopes — elements that are chemically indistinguishable, but differ in their atomic masses — exhibit some peculiar behavior. A pair of isotopes contains the same number of protons, but a different number of neutrons, or vice versa. A consequence of this is an increase in a nucleus...
This is done a variety of ways, which include injection into a vein, inhalation, or drinking a liquid that contains the isotope. The type of isotope used and the way it enters into the body depends on the body part that is targeted. PET scans use isotopes to highlight functions inside...

Medical radioisotopes such as iodine also lie outside what is known as the band of stability, but, in this case, they offer beneficial characteristics. Iodine-131 has four extra neutrons than its stable counterpart, and has a half-life of eight days. Since iodine can be safely ingested, it...
