Beryllium: The Lightest Of The Alkaline-Earth Metals

Discovery Beryllium was discovered as the oxide in 1798 by Nicolas-Louis Vauquelin in beryl and in emeralds, and it was isolated as the independent metal in 1828 by Antoine A.B. Bussy, by the reduction of its chloride with potassium. The name was derived from the Greek word for beryl (berryllo). At one time, it was

Dilead(II) Lead(IV) Oxide (How It Was Named)

How It Was Named In chemical reactions, dilead(II) lead(IV) oxide functions as a mixed oxide (lead(IV) oxide and dilead(II) oxide). Combining the names of the two compounds, we have: Dilead(II) lead(IV) oxide. The lower oxide is recognised first. It is also known as lead(II,IV) oxide, red lead and red lead oxide.

Boron: An Aid For Building Muscles

Discovery Boron was discovered by Louis-Josef Gay-Lussac and Louis-Jacques Thénard (French chemists) in Paris, France, and by Humphry Davy (English chemist) in London, UK in 1808. The name of the element was derived from the Arabic word “buraq”, which was the name for borax. Melting and Boiling Points Melting point: 2,076 °C (2,349.15 K). Boiling
