Properties and data of the isotope 186 Os. Osmium isotopes. ½ 2.0 (11) × 1015 a 6.3072 × 1022 seconds s. 186 Ir 186 Re 190 Pt. The following table shows the atomic nuclei that are isotonic (same neutron number N = 110) and isobaric (same nucleon number A = 186) with Osmium-186.

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.

Osmium (from Ancient Greek ὀσμή (osmḗ) 'smell') is a chemical element; it has symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores. Osmium is the densest naturally occurring element.

Natural osmium deposits are composed of 7 isotopes, two of which are unstable radioisotopes: All other osmium nuclides known and characterized so far are unstable. The two following tables list the most important data and properties of the Osmium isotopes.

In 1991, the Commission considered new isotope measurements yielding an atomic weight having a significantly improved precision, and recommended Ar (Os) = 190.23 (3). One of the minor isotopes, 186 Os, is radioactive with a very long half-life of 2.0×10 15 a.
