Quick Answer
Frederick Soddy introduced the concept of isotopes in 1913. He showed that atoms can have the same chemical identity but different masses.
The Full Story
Frederick Soddy coined the term isotopes in 1913 while studying radioactive elements. He realized that different atoms could occupy the same place in the periodic table yet have different atomic masses. This idea explained why some elements seemed chemically identical but behaved differently in mass measurements. Soddy’s insight was crucial for modern atomic theory and earned him the Nobel Prize in Chemistry in 1921.
