Gallium(Ga) atomic and molecular weight, atomic number and elemental symbol Gallium is a Block P, Group 13, Period 4 element. The number of electrons in each of Gallium's shells is 2, 8, 18, 3 and its electronic configuration is [Ar] 3d10 4s2 4p1. In its elemental form gallium's CAS number is 7440-55-3. The gallium atom has a radius of 122.1.pm and it's Van der Waals radius is 187.pm. Gallium is not toxic. Gallium is one of three elements that naturally occur as a liquid at room temperature. The other two are mercury and cesium. The application of gallium that has received the most attention is the production of semiconducting compounds. Of these, the Gallium Bohr ModelmostElemental Gallium important are the compounds of gallium with antimony, arsenic or phosphor. Nowadays gallium arsenide (Ga-As) is undoubtedly the most used. This compound is used in the production of several electronic parts such as diodes and transistors, made for voltage rectification, signal amplification, etc. Other gallium arsenide applications are the semiconductor "lasing" and microwave generation and also in sensors to measure temperature, light or magnetic field. Gallium was first discovered by Hans Christian Oersted in 1825. See Gallium research below.

Lithium(Li) atomic and molecular weight, atomic number and elemental symbol Lithium is a Block S, Group 1, Period 2 element. The number of electrons in each of Lithium's shells is 2, 1 and its electronic configuration is [He] 2s1. In its elemental form lithium's CAS number is 7439-93-2. The lithium atom has a radius of 152.pm and it's Van der Waals radius is 182.pm. Lithium is toxic and corrosive. Lithium is a member of the alkali group of metals. It has the highest specific heat of any material and the highest electrochemicalLithium Bohr Model potential. This makes it important in applications involving heat transfer and as the anode in batteries. Lithium is available as metal and compounds with purities from 99% to 99.999% Elemental Lithium(ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Lithium is a dopant in advanced optical glass. It is used as an alloy in light weight metals. Lithium stearate is a common high temperature lubricant. Lithium was first discovered by Johann Arvedson in 1817. The origin of the name Lithium comes from the Greek word lithose which means "stone". See Lithium research below.
