Osmium (from Greek osme (ὀσμή) meaning "smell") is a chemical element with 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 a density of 7004225900000000000♠22.59 g/cm3. Its alloys with platinum, iridium, and other platinum group metals are employed in fountain pen nibs, electrical contacts, and other applications where extreme durability and hardness are needed.
Osmium has a blue-gray tint and is the densest stable element, slightly denser than iridium. Calculations of density from the X-ray diffraction data may produce the most reliable data for these elements, giving a value of 7004225620000000000♠22.562±0.009 g/cm3 for iridium versus 7004225870000000000♠22.587±0.009 g/cm3 for osmium.
Osmium is a hard but brittle metal that remains lustrous even at high temperatures. It has a very low compressibility. Correspondingly, its bulk modulus is extremely high, reported between 7002395000000000000♠395 and 7011462000000000000♠462 GPa, which rivals that of diamond (7011443000000000000♠443 GPa). The hardness of osmium is moderately high at 7009400000000000000♠4 GPa. Because of its hardness, brittleness, low vapor pressure (the lowest of the platinum group metals), and very high melting point (the fourth highest of all elements), solid osmium is difficult to machine, form, or work.

Part 76 of the 92 part series: The Naturally Ocuring Elements. An entertaining overview of the element Osmium, sponsered by the American Scientific Institution of America. Talks about the properties of the element and the history. Directed by: Allen Wengert. Chemistry project for winter 2008.
Osmium is the debut album of American funk band Parliament, led by George Clinton. The album has a psychedelic soul sound with a spirit of experimentation that is more similar to early Funkadelic than the later R&B-inspired; Parliament albums. It was originally released in July 1970 on Invictus Records.[5] The original vinyl release contained a glossy lyric sheet. Since its re-release in 1990, Osmium has been distributed numerous times by various labels in the U.S., Europe and Japan, sometimes under alternate titles that have included Rhenium and First Thangs. A number of these reissues have featured material that was not included on the original album, such as unreleased tracks and singles that were recorded around the same time as Osmium. The personnel for this album included the five P...

I will wake you up at night.I won't write curses on your
door.
I will stick to the fact that nobody's angry anymore.
You'll start weeping in the dark.
I'll stop saying you're a whore.
I will stick to the fact that you don't love me anymore.
It's so easy to break up,
'Cause we know we didn't match up.
And we're always amazed when we look at the craziness
tearing us apart.
Yes, it's so easy to break up,
'Cause we know we didn't match up.
And we're always amazed when we look at the craziness
tearing us apart, all apart.
You're not that lovely, not that bright.
I finally get happy when you're out of sight.
Please, let's stick to the fact that it is time to turn
off the light.
I have memories of what's been done
I try to find good ones, but there are none.
Please, let's stick to the fact that it is time to forget
the fight.
It's so easy to break up,
'Cause we know we didn't match up.
And we're always amazed when we look at the craziness
tearing us apart.
Yes, it's so easy to break up,
