4, 1913, issue of Nature, English radiochemist Frederick Soddy proposed the isotope concept—that elements could have more than one atomic weight. The idea led to his 1921 Nobel Prize in Chemistry.
Who is responsible for isotopes?
It was Frederick Soddy, who first proposed the word isotopes in 1913. The hydrogen atom is the simplest of all atoms: it consists of a single proton and a single electron. In addition to the most common form of the hydrogen atom that is called protium, two other isotopes of hydrogen exist: deuterium and tritium.
Who discovered isotopes and isobars?
The radiochemist Frederick Soddy was the one who discovered the isotopes.
What led to the discovery of isotopes?
Evidence for the existence of isotopes emerged from two independent lines of research, the first being the study of radioactivity. By 1910 it had become clear that certain processes associated with radioactivity, discovered some years before by French physicist Henri Becquerel, could transform one element into another.
