most abundant metallic element. Aluminum's name is derived from

alumina, the mineral from which Sir Humphrey Davy attempted to refine it from

in 1812. It wasn't until 1825 that Aluminum was first isolated by Hans Christian

Oersted. Aluminum is a silvery gray metal that possesses many desirable

characteristics. It is light, nonmagnetic and non-sparking. It stands second

amongmetals in the scale of malleability, and sixth in ductility. It is extensively

used in many industrial applications where a strong, light, easily constructed

material is needed. Although it has only 60% of the electrical

conductivity ofcopper, it is used in electrical transmission lines because of its

light weight. Pure aluminum is soft and lacks strength, butalloyed with small

amounts ofcopper,magnesium,silicon,manganese, or other elements it

imparts a variety of useful properties. Aluminum was first predicted by Antoine

Lavoisierin 1787 and first isolated by Friedrich Wöhler in 1827. For more

Chromium (atomic symbol: Cr, atomic number: 24) is a Block D, Group 6,

Period 4 element with an atomic weight of 51.9961. The number of

electrons in each of Chromium's shells is 2, 8, 13, 1 and its electron

configuration is [Ar] 3d5 4s1. Chromium was first discovered by Louis Nicolas

Vauquelin in 1797. It was first isolated in 1798, also by Louis Nicolas

Vauquelin. The chromium atom has a radius of 128 pm and a Van der Waals

radius of 189 pm. In its elemental form, chromium has a lustrous steel-gray

appearance. Chromium is the hardestmetal element in the periodic

table and the only element that exhibits antiferromagnetic ordering at room

temperature, above which it tranforms into a paramagnetic solid. The most

common source of chromium is chromite ore (FeCr2O4). Due to its various

colorful compounds, Chromium was named after the Greek word 'chroma'

meaning color. For more information on chromium, including properties, safetydata, research, and American Elements' catalog of chromium products, visit
