The element and its compounds are highly toxic. Can someone give me 5 chemical properties of Osmium? In the lithosphere, the estimated concentration of platinum group metals range from 0.05 to 0.5 ppm(2). It does not tarnish at room temperatures, but oxidises in air at about 800°C. Reacts with hydrochloric acid to form toxic chlorine gas. It is used in fountain pen tips. This pale-yellow compound has a … The metal is neither affected by … When heated, the metal combines with oxygen to form osmium tetroxide (OsO 4 ). Chemical reactions.

The osmium of OsO 4 has an oxidation number of VIII; however, the metal does not possess a corresponding 8+ charge as the bonding in the compound is largely covalent in character (the ionization energy required to produce a formal 8+ charge also far exceeds the energies available in normal chemical reactions).

Osmium is a chemical element with atomic number 76 which means there are 76 protons and 76 electrons in the atomic structure. Chemical Characteristics. Even the man who discovered osmium treated it rather sniffily. There are various oxidation states of osmium, ranging from -2 to +8, and the most common are +2, +3 and +8. There are various oxidation states of osmium, ranging from -2 to +8, and the most common are +2, +3 and +8. A gray-white metal, osmium is very hard, brittle, and difficult to work, even at high temperatures.
