WebMar 22, 2024 · The name isotope (from the Greek for “same place”) was suggested by the British chemist Frederick Soddy in 1913 for these different radioactive forms of the same chemical species, because they could be classified in the same place in the periodic table of the elements. The ion of mass 22 was, in fact, a stable heavy isotope of neon. WebIsotopes are atoms of the same element with different numbers of neutrons. Because they contain different numbers of neutrons, isotopes have different atomic masses. The average atomic mass of an element is calculated by taking the weighted average mass of the element's naturally occurring isotopes. Created by Sal Khan. Sort by: Top Voted Questions
