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. The element name originated from the Latin word 'aurum' meaning gold. See Gold research below.

Copper(Cu) atomic and molecular weight, atomic number and elemental symbolCopper is a Block D, Group 11, Period 4 element. The number of electrons in each of Copper's shells is 2, 8, 18, 1 and its electronic configuration is [Ar] 3d10 4s1. In its elemental form copper's CAS number is 7440-50-8. The copper atom has a radius of 127.8 .pm and it's Van der Waals radius is 140.pm. Copper is an essential trace element in animals and plants, but in excess copper is toxic. Due to its high electrical conductivity, large amounts of copper are used by the electrical industry for wire. Of all pure metals, only silver has a higher electrical conductivity. Copper is also resistant to corrosion caused by moisture, making it a widely used material in pipes, coins, and jewelry. Copper is often too soft for its applications, so it is incorporated in numerous alloys. For example, brass is a copper-zinc alloy, and bronze is a copper-tin alloy. Copper sulfate (CuSO 4·H2O), also known as blue vitrol, is the most well-known Elemental Coppercopper compound. It is used as Copper Bohr Modelan agricultural poison, an algicide, and as a pigment for inks. Cuprous chloride (CuCl) is a powder used to absorb carbon dioxide (CO2). Copper cyanide (CuCN) is often used in electroplating applications. Copper is available as 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. Copper was first discovered by Early Man. The origin of the word copper comes from the Latin word 'cuprium' which translates as "metal of Cyprus". Cyprus, a Mediterranean island, was known as an ancient source of mined copper. See Copper research below.
