Aluminum is a Block P, Group 13, Period 3 element. The number of electrons in each of Aluminum's shells is 2, 8, 3 and its electronic configuration is [Ne] 3s2 3p1. In its elemental form aluminum's CAS number is 7429-90-5. The aluminum atom has a radius of 143.2.pm and it's Van der Waals radius is 200.pm. Aluminum is not known to be harmful but ingestion may cause Alzheimer's disease.Aluminum is a silvery-white metal that possesses many desirable characteristics. It is light, nonmagnetic and nonsparking.
It stands second among metals 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's electrical conductivity is only about 60% that of copper, it is used in electrical transmission lines because of its light weight. Pure aluminum is soft and lacks strength, but alloyed with small amounts of copper, magnesium, silicon, manganese, or other elements impart a variety of useful properties. These alloys are of vital importance in the construction of modern aircraft and rockets. Aluminum, evaporated in a vacuum, forms a highly reflective coating for both visible light and radiant heat. They are used to coat telescope mirrors. Aluminum 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. See Aluminum research below.
Beryllium is a Block S, Group 2, Period 2 element. The number of electrons in each of Beryllium's shells is 2, 2 and its electronic configuration is [He] 2s2. In its elemental form beryllium's CAS number is 7440-41-7. The beryllium atom has a radius of 111.3.pm and it's Van der Waals radius is 200.pm. Beryllium and its salts are toxic as well as carcinogenic. Beryllium is most commonly used in alloys with our base metallic materials. As a 1 - 3% addition to copper it produces "beryllium bronze", a highly wear resistant material and with nickel it is used to make spot welder electrodes. Beryllium 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. It is used as a coating on X-ray tubes because it is transparent to the X-ray range. It emits neutrons on bombardment by alpha rays. It also has applications in the nuclear industry. Beryllium was first discovered by Abbé René-Just Hauy in 1798. The origin of the name Beryllium comes from the Greek word 'beryllos' meaning beryl. See Beryllium research below.
