Isotones

Definition

Isotones are nuclei that have the same number of neutrons but different numbers of protons. This means that isotones belong to different elements, which leads to variations in nuclear charge and mass. Understanding isotones is important as they exhibit distinct physical properties and behaviors due to their differing proton counts while maintaining the same neutron count.
