Potassium(K) atomic and molecular weight, atomic number and elemental symbolPotassium is a Block S, Group 1, Period 4 element. The number of electrons in each of Potassium's shells is 2, 8, 8, 1 and its electronic configuration is [Ar] 4s1. In its elemental form potassium's CAS number is 7440-09-7. The potassium atom has a radius of 227.2 .pm and it's Van der Waals radius is 275.pm. Potassium is not toxic. Potassium is the seventh most abundant element on earth. In its metallic form it is one of the most reactive and Potassium Bohr Modelelectropositive of all metals and rapidly oxidizes. As with other metals of the alkali group, the metal Elemental Potassiumdecomposes in water with the evolution of hydrogen. It catches fire spontaneously in water. In high purity, potassium compounds have numerous pharmacological, medical, and electronics applications. Important compounds include the hydroxide, nitrate, carbonate, chloride, bromide, iodide, and sulfate. Lower purity compounds are used in pyrotechnics for its violet color on ignition and in glass and ceramic glazes to produce this color. Potassium also used as a nutrient in plant growth. Potassium was first discovered by Sir Humphrey Davy in 1807. The origin of the element name comes from the English word 'potash' meaning pot ashes and the Arabic word 'qali' which means alkali. The symbol K originates from the Latin word 'kalium'. See Potassium 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.
