Platinum(Pt) atomic and molecular weight, atomic number and elemental symbolPlatinum is a Block D, Group 10, Period 6 element. The number of electrons in each of Platinum's shells is 2, 8, 18, 32, 17, 1 and its electronic configuration is [Xe] 4f14 5d9 6s1. In its elemental form platinum's CAS number is 7440-06-4. The platinum atom has a radius of 137.3.pm and it's Van derWaals radius is 172.pm. Platinum is not toxic. Platinum is a member of the platinum group of metals. It is highly corrosion resistant and has numerous catalytic applications. These include in petrochemical cracking catalysts, automotive catalytic converters and in the processes used for proton exchange membrane fuel cells. The metal does Elemental Platinumnot oxidize in air at anyPlatinum Bohr Model temperature. The metal is extensively used in jewelry, electronic wire, and crucibles for corrosive and high temperature laboratory uses and in many advanced instruments. Platinum compounds have application in medicine. Platinum 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. Platinum was first discovered by Julius Scaliger in 1735. The origin of the name comes from the Spanish word platina meaning silver. See Platinum research below.

Rhodium(Rh) atomic and molecular weight, atomic number and elemental symbolRhodium is a Block D, Group 9, Period 5 element. The number of electrons in each of Rhodium's shells is 2, 8, 18, 16, 1 and its electronic configuration is [Kr] 4d8 5s1. In its elemental form rhodium's CAS number is 7440-16-6. The rhodium atom has a radius of 134.5.pm and it's Van der Waals radius is 200.pm. Rhodium is not toxic. Rhodium is a member of the platinum group of metals. It has a higher melting point than platinum, but a lower Rhodium Bohr Modeldensity. It is alloyed with platinum and palladium in electrodes for spark plugs, advanced laboratory equipment and in thermocouples. Rhodium compounds also have catalytic uses in automotive catalytic converters. Rhodium is used as a plating metal in jewelry production to enhance the whiteness of white gold. Rhodium 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. Rhodium was first discovered by William Wollaston in 1803. The name Rhodium, originates from the Greek word 'Rhodon' which means rose. See Rhodium research below.
