Correct Answer

A. Frederick Soddy

Explanation

Frederick Soddy is credited with introducing the term "isotope." He was a British chemist who made significant contributions to the understanding of radioactivity and the concept of isotopes. Soddy's work laid the foundation for the development of the modern theory of atomic structure and the discovery of isotopes. His research on radioactive decay and the identification of different forms of elements with the same atomic number but different atomic weights led him to coin the term "isotope" in 1913. This term is now widely used in the field of chemistry to describe atoms of the same element with different numbers of neutrons.
