Isotones

Definition

Isotones are nuclides that have the same number of neutrons but different numbers of protons. This means that isotones belong to different elements, as the number of protons defines the element, while the number of neutrons affects the stability and mass of the nucleus. Understanding isotones is important in analyzing nuclear stability and how different isotopes can exhibit various radioactive behaviors.
