Isotopes
Overview
Isotopes are variations of a particular chemical element that have the same number of protons but a different number of neutrons in their nuclei. This difference in neutron number results in isotopes having different atomic masses, but they share the same chemical properties. Isotopes can be stable or radioactive, with unstable isotopes undergoing radioactive decay. The concept of isotopes was first introduced in the early 20th century, providing a deeper understanding of atomic structure and chemistry. Isotopes have diverse applications in fields ranging from medicine to archaeology and nuclear power.

Early History
The term "isotopes" was introduced by Frederick Soddy, an English chemist, in 1913 to describe atoms of the same element that have different atomic masses but exhibit identical chemical behavior. The concept was integral to the development of atomic theory, shifting the understanding of elemental composition. Initially, isotopes were simply identified in elements with known radioactivity, leading to the discovery of various isotopes through spectrometry and other analytical techniques. Many historical milestones were associated with the study of isotopes, such as the understanding of radioactive decay series and the realization of isotopic abundance in nature.
