The word "beryllium" comes from the Greek word beryllos, which means "green gemstone" or "beryl ore". The name was first used in English in 1797 by Sir Humphry Davy. 
 
Before it was named beryllium, the element was known as glucinium, which comes from the Greek word glykys meaning "sweet". This was because early chemists thought the element had a sweet taste and tasted it to determine its properties. However, they later discovered that beryllium is highly toxic and should never be tasted. 
 
In 1949, IUPAC chose beryllium as the official name for the element, which became official in 1957. 
 
Beryllium is a steel-gray metal with many desirable properties, including high melting point, high tensile strength, and excellent thermal and electrical conductivity. It is used in a variety of applications, including as an alloying agent in beryllium copper, and as a structural material in aircraft, missiles, spacecraft, and communication satellites.
