Tin-98

Properties and data of the isotope ⁹⁸Sn.

Contents

Tin-98 is a radioisotope of the chemical element tin, which has 48 neutrons in its atomic nucleus in addition to the element-specific 50 protons; the sum of the number of these atomic nucleus building blocks results in a mass number of 98. The very short-lived, only artificially produced, unstable and thus radioactive nuclide has no practical significance; the study of ⁹⁸Sn is exclusively for academic purposes.
