jan 1, 1892 - Discovery Isotopes

Description:

Frederick Soddy discovered Isotopes based on how uranium decays to radium, he showed that a radioactive element may have more than one in its atomic mass thought the chemical properties are identical. Therapeutic use of radioisotopes is intended to destroy targeted cells. Isotopes are commonly used in medical imaging and cancer treatment, radioisotopes typically have short half-lives and can decay before the emitted radioactivity can cause damage to the patients' body. Isoptopes are atoms that have the saem numbers of protons but different numbers of neutrons.
