Osmium is a Block D, Group 8, Period 6 element. The number of electrons in each of Osmium's shells is 2, 8, 18, 32, 14, 2 and its electronic configuration is [Xe] 4f¹⁴ 5d⁶ 6s². In its elemental form osmium's CAS number is 7440-04-2. The osmium atom has a radius of 133.8.pm and it's Van der Waals radius is 200.pm. Osmium tetroxide (OsO₄) can cause eye, lung and skin damage which makes it very toxic. Osmium has the highest melting point and the lowest vapor pressure of any of the platinum group of metals. Osmium tetroxide has recently been used to detect fingerprints and as an aid to stain fatty tissue for microscope slides. The metal is almost entirely used to produce very hard alloys with other metals of the platinum group. Osmium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Osmium was first discovered by Smithson Tennant in 1803. The origin of the name Osmium comes from the Greek word osme meaning a smell or odor. See Osmium research below.

Phosphorus is a Block P, Group 15, Period 3 element. The number of electrons in each of Phosphorus's shells is 2, 8, 5 and its electronic configuration is [Ne] 3s² 3p³. In its elemental form Phosphorus's CAS number is 7723-14-0. The Phosphorus atom has a radius of 110.5.pm and it's Van der Waals radius is 180.pm. Although white phosphorus is very toxic, red phosphorus is not considered toxic. Phosphorus information, including Technical Data, Safety Data and its High Purity properties, research, applications and other useful facts are discussed below. Scientific facts such as the atomic structure, ionization energy, abundance on Earth, conductivity and thermal properties are included.
