Osmium (76 Os) has seven naturally occurring isotopes, five of which are stable: 187 Os, 188 Os, 189 Os, 190 Os, and (most abundant) 192 Os. The other natural isotopes, 184 Os, and 186 Os, have extremely long half-life (1.12×10 13 years and 2×10 15 years, respectively) and for practical purposes can be considered to be stable as well.
