Sodium(Na) atomic and molecular weight, atomic number and elemental symbolSodium 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 Sodium Bohr Modelchemical 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.

Gold(Au) atomic and molecular weight, atomic number and elemental symbol Gold is a Block D, Group 11, Period 6 element. The number of electrons in each of Gold's shells is 2, 8, 18, 32, 18, 1 and its electronic configuration is [Xe] 4f142 5d10 6s1. In its elemental form gold's CAS number is 7440-57-5. The gold atom has a radius of 144.2.pm and it's Van der Waals radius is 166.pm. Gold is not toxic. Gold is a soft metal and is usually alloyed to give it more strength. It is a good conductor of heat and electricity, and is unaffected by air and most reagents. It is used in coinage and is a standard for monetary systems. It is also extensively used for jewelry, dental work, Elemental Goldand for plating It is used for coating certain space satellites, as it Gold Bohr Modelis a good reflector of infrared and is inert. One area that has seen significant growth is the use of gold in electronics, particularly within telecommunications, information technology and safety critical applications. Similarly, within computers there are usually gold-plated edge connectors. Gold bonding wires are used extensively within semiconductor packages, gold thick film inks are applied in the fabrication of hybrid circuits and gold's excellent solder wetting properties are used to form a very thin protective layer on copper laminate printed circuit boards. Gold was first discovered by Early Man c.a. 3000. See Gold research below.
