Sodium is a Block S, Group 1, Period 3 element. The number of electrons in each of Sodium's shells is 2, 8, 1 and its electronic configuration is [Ne] 3s1. In its elemental form sodium's CAS number is 7440-23-5. The sodium atom has a radius of 185.8.pm and it's Van der Waalsradius is 227.pm. Sodium is not toxic but skin contact may cause irritation and burns. Sodium is primarily used in its metallic form in the production of chemical esters and in the manufacturing of various other organic compounds. The metal is used in the alloy of tin, nickel and copper for its structural characteristics. Sodium is availableas metal and compounds with purities from 99% to 99.9999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. High purity sodium compounds are used as reducing agents. Sodium compounds are used in low tech applications throughout industry. Sodium was first discovered by Sir Humphrey Davy in 1807. The name Sodium comes from the Latin word "natrium" which means sodium carbonate. See Sodium research below.
Rhodium 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 density.
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.
