Platinum Group Isotope

  • Isotopes of platinum - Wikipedia

    2019-11-04  Natural platinum (78 Pt) occurs in five stable isotopes (192 Pt, 194 Pt, 195 Pt, 196 Pt, 198 Pt) and one very long-lived (half-life 6.50×10 11 years) radioisotope (190 Pt). There are also 34 known artificial radioisotopes, the longest-lived of which is 193 Pt with a half-life of 50 years.
