The densities of ordinary substances here on earth (as opposed to such things as gases at very low pressures or white dwarf stars) vary from the least dense, hydrogen gas, with a density of 0.000 089 grams per cubic centimeter to the element osmium which, at 22 grams per cubic centimeter, is only slightly more dense...

Osmium was discovered by Smithson Tennant (England) in 1803. The origin of the name comes from the Greek word osme meaning smell. It is hard fine black powder or hard, lustrous, blue-white metal. Unaffected by air, water and acids.

Permanganate hydroxylation follows the (3 + 2) cycloaddition mechanism established earlier for osmium tetroxide. Density functional theory (Becke3LYP/6-31G*) predicts that the concerted (3 + 2) pathway is favored by about 40 kcal/mol relative to a stepwise process involving a (2 + 2) cycloaddition. ...
