Explanation:
Osmium (from Greek ὀσμή osme, "smell") is a chemical element with the 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, with an experimentally measured (using x-ray crystallography) density of 22.65 g/cm3. Manufacturers use its alloys with platinum, iridium, and other platinum-group metals to make fountain pen nib tipping, electrical contacts, and in other applications that require extreme durability and hardness.[3] The element's abundance in the Earth's crust is among the rarest, with an abundance of only 50 ppt in the earth's crust.[4][5] It is estimated to be about 0.6 parts per billion in the universe and is therefore the rarest precious metal.
