Silver(Ag)atomic and molecular weight, atomic number and elemental symbolSilver 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, Elemental Silverand possesses the lowest contact resistance. It is stable in pure air and water, but tarnishes when Silver Bohr Modelexposed 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.

Selenide(Se) atomic and molecular weight, atomic number and elemental symbolSelenium is a Block P, Group 16, Period 4 element. The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electronic configuration is [Ar] 3d10 4s2 4p4. In its elemental form selenium's CAS number is 7782-49-2. The selenium atom has a radius of 116.pm and it's Van der Waals radius is 190.pm. The EPA does not classify selenium as carcinogenic, although selenium sulfide Elemental Seleniumis a probable carcinogen. Selenates and selenites which are compounds of selenium, are highly toxic. Hydrogen selenide gas (SeH2) is the most acutely toxic compound of selenium. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. of photocells and exposure meters for photographic use, as Selenium Bohr Modelwell as solar cells. Below its melting point, selenium is a p-type semiconductor and has many uses in electronic and solid-state applications. Selenium 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. Selenium was first discovered by Jons Berzelius in 1817. The origin of the name Selenium comes from the Greek word "Selęnę" meaning moon. See selenium research below.
