Osmium (Os)
One of the platinum group metals, osmium ([Xe]4f145d66s2) (CAS 7440-04-2) is bluish-white, lustrous, extremely hard, and brittle. Its properties make it ideal for combining with other platinum metals to produce very hard alloys. Osmium has the highest melting point and lowest vapor pressure of the platinum group and it is very difficult to fabricate. While osmium powder or sponge is affected by air at room temperature, the metal is relatively inert in ambient conditions.

Primary XPS region: Os4f Overlapping regions: Zr4s, Fe3p, Ir3p, Li1s, Pt5p3 Binding energies of common chemical states:, N/A, N/A, Os4d peaks overlap with C1s region, necessitating careful peak fitting.
Geochronology involves understanding time in relation to geological events and processes. Geochronological investigations examine rocks, minerals, fossils and sediments. Absolute and relative dating approaches complement each other.
