Beryllium was discovered by Louis-Nicolas Vauquelin in 1798 as a component of beryl and in emeralds. Friedrich Wöhler and Antoine Bussy independently isolated the metal in 1828 by reacting potassium and beryllium chloride. Beryllium's chemical similarity to aluminum was probably why beryllium was missed in previous searches. CHARACTERISTICS

Beryllium is an element, also known on the periodic table as Be with the atomic number of 4 and 9.012 as the atomic mass. Beryllium is naturaly found combined with other elements of the periodic table in minerals. Expensive gemstones that contain Beryllium aquarium and emerald. This element blongs to the alkalie earth metals family and/or group along with Magnesium(atomic number 4). This element is a gray-colored solid, steel, strong, lightweight fragile alkaline earth metals. Beryllium is normally used as a alloy hardener. Beryllium has a very low desity, roughly around 1.85 times that of water, it has a melting point of 2332*F(1278 °C). Beryllium is a hard metal that is extracted from the earth. It happens to be a chemical component of certain rocks (bertrandite and beryl), coal and oil, soil, and volcanic dust. Beryllium’s light weight, high tensile strength and ability to slow neutrons have made it useful for many purposes. Beryllium is used in aircraft disc brakes, nuclear weapons and reactors, missile parts, heat shields, x–ray machine parts, mirrors and spacecraft.
