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, and for plating It is used for coating certain space satellites, as it is 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.
Platinum is a Block D, Group 10, Period 6 element. The number of electrons in each of Platinum's shells is 2, 8, 18, 32, 17, 1 and its electronic configuration is [Xe] 4f14 5d9 6s1.

Platinum is a member of the platinum group of metals. It is highly corrosion resistant and has numerous catalytic applications. These include in petrochemical cracking catalysts, automotive catalytic converters and in the processes used for proton exchange membrane fuel cells. The metal does not oxidize in air at any temperature. The metal is extensively used in jewelry, electronic wire, and crucibles for corrosive and high temperature laboratory uses and in many advanced instruments. Platinum compounds have application in medicine. Platinum 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. Platinum was first discovered by Julius Scaliger in 1735. The origin of the name comes from the Spanish word platina meaning silver. See Platinum research below.

Silver is a Block D, Group 11, Period 5 element. The number of electrons in each of Silver's shells is 2, 8, 18, 18, 1 and its electronic configuration is [Kr]4d10 5s1. In its elemental form silver's CAS number is 7440-22-4. The silver atom has a radius of 144.5.pm and it's Van der Waals radius is 144.pm. Silver is not toxic although most silver salts are poisonous. Silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals, and possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when exposed to ozone, hydrogen sulfide, or air containing sulfur. Silver nitrate has wide application in painting, xerography, chemical electroplating, in components for electric batteries and in medicine as catalyst. Silver chloride is another important compound, due to its ductility and malleability. The organic compounds of the element are used in the coating of several metals and in dynamite or other explosive bars. Metallic silver is used as a catalyst of several oxidation reactions such as those of ethanol and other alcohols. Silver 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. Silver was first discovered by Early Man. Silver was named after the Anglo-Saxon word "seolfor" or "siolfur" meaning 'silver'. See Silver research below.
Indium is a Block P, Group 13, Period 5 element. The number of electrons in each of Indium's shells is 2, 8, 18, 18, 3 and its electronic configuration is [Kr] 4d10 5s2 5p1. In its elemental form indium's CAS number is 7440-74-6. The indium atom has a radius of 162.6.pm and it's Van der Waals radius is 193.pm. Indium is only slightly toxic. Indium has found application in semi-conductor materials and other electronic applications. It is used to make low-melting alloys, such as an alloy of 24% indium - 76% Indium is liquid at room temperature. It is used in making bearing alloys, germanium transistors, rectifiers, and photoconductors. It can be plated onto metal and evaporated onto glass, forming a mirror as good as that made with silver but with more resistance to atmospheric corrosion. Indium 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. Indium is also used in various metal alloys (See AE Alloys). Indium was first discovered by Ferdinand Reich in 1863. See Indium research below.

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, 
and for plating It is used for coating certain space satellites, as it 
is 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. 
Platinum is a Block D, Group 10, Period 6 element. The number of electrons in each of Platinum's shells is 2, 8, 18, 32, 17, 1 and its electronic configuration is [Xe] 4f14 5d9 6s1. In its elemental form platinum's CAS number is 7440-06-4. The platinum atom has a radius of 137.3.pm and it's Van derWaals radius is 172.pm. Platinum is not toxic. Platinum is a member of the platinum group of metals. It is highly corrosion resistant and has numerous catalytic applications. These include in petrochemical cracking catalysts, automotive catalytic converters and in the processes used for proton exchange membrane 
not oxidize in air at any
temperature. The metal is extensively used in jewelry, electronic wire, and crucibles for corrosive and high temperature laboratory uses and in many advanced instruments. Platinum compounds have application in medicine. Platinum 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. Platinum was first discovered by Julius Scaliger in 1735. The origin of the name comes from the Spanish word platina meaning silver. See Platinum research below. Platinum compounds have application in medicine. Platinum 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.
Palladium is a Block D, Group 10, Period 5 element. The number of electrons in each of Palladium's shells is 2, 8, 18, 18 and its electronic configuration is [Kr] 4d10. In its elemental form palladium's CAS number is 7440-05-3. The palladium atom has a radius of 137.6.pm and it's Van der Waals radius is 163.pm. Palladium is a member of the palladium group of metals. It is an excellent hydrogenation and 
dehydrogenation
catalyst and available in many Organo-metallic forms for this purpose. It is alloyed with gold, silver, iridium and other palladium group elements and used in jewelry. The metal is used in dentistry, watch making, and in making surgical instruments and electrical contacts. Palladium 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. Palladium was first discovered by William Hyde Wollaston in 1803. See Palladium research below. Palladium was first discovered by William Hyde Wollaston in 1803. See Palladium research below.
Silver is a Block D, Group 11, Period 5 element. The number of electrons in each of Silver's shells is 2, 8, 18, 18, 1 and its electronic configuration is [Kr]4d10 5s1. In its elemental form silver's CAS number is 7440-22-4. The silver atom has a radius of 144.5.pm and it's Van der Waals radius is 144.pm. Silver is not toxic although most silver salts are poisonous. Silver has a brilliant white metallic luster. It is a little harder than gold and is very ductile and malleable, being exceeded only by gold and perhaps palladium. Pure silver has the highest electrical and thermal conductivity of all metals, 
and possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when 
exposed to ozone, hydrogen sulfide, or air containing sulfur. Silver nitrate has wide application in painting, xerography, chemical electroplating, in components for electric batteries and in medicine as catalyst. Silver chloride is another important compound, due to its ductility and malleability. The organic compounds of the element are used in the coating of several metals and in dynamite or other explosive bars. Metallic silver is used as a catalyst of several oxidation reactions such as those of ethanol and other alcohols. Silver 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. Silver was first discovered by Early Man. Silver was named after the Anglo-Saxon word "seolfor" or "siolfur" meaning 'silver'. See Silver research below.
Indium is a Block P, Group 13, Period 5 element. The number of electrons in each of Indium's shells is 2, 8, 18, 18, 3 and its electronic configuration is [Kr] 4d10 5s2 5p1. In its elemental form indium's CAS number is 7440-74-6. The indium atom has a radius of 162.6.pm and it's Van der Waals radius is 193.pm. Indium is only slightly toxic. Indium has found application in semi-conductor materials and other electronic applications. 
It is used to make low-melting alloys, such as an alloy of 24% indium - 76% Indium is liquid at room temperature. It is used in making bearing alloys, germanium transistors, rectifiers, and photoconductors. It can be plated onto metal and 
evaporated onto glass, forming a mirror as good as that made with silver but with more resistance to atmospheric corrosion. Indium 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. Indium is also used in various metal alloys (See AE Alloys). Indium was first discovered by Ferdinand Reich in 1863. See Indium research below.
