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.
Tantalum is a Block D, Group 5, Period 6 element. The number of electrons in each of Tantalum's shells is 2, 8, 18, 32, 11, 2 and its electronic configuration is [Xe] 4f14 5d3 6s2. In its elemental form tantalum's CAS number is 7440-25-7. The tantalum atom has a radius of 143.pm and it's Van der Waals radius is 200.pm. Tantalum is not toxic. Tantalum has a number of interesting properties that make it particularly useful in electronic applications. Tantalum 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. It has the third highest melting point, surpassed only by rhenium and tungsten, yet it is highly conductive to heat and electricity. This has made it the material of choice for electronic capacitors for most telecommunications and hand held electronics equipment, such as cell phones, laptop computers and pagers. Tantalum compounds, such as the oxide and chloride, are the basis for di-electric coatings. Tantalum is added to glass for its high refractive index. It has various applications in nuclear energy. Due to the close relation of tantalum to niobium in the periodic table, Tantalum's name originates from the Greek word Tantalos meaning Father of Niobe in Greek mythology. See Tantalum research below. See Tantalum research below.
