INTRODUCTION
Beryllium is not very popular,partly because it is not very abundant and partly because it is difficult to extract.Since it's soluble compounds are sweet-tasting,it was first called glucinium, a reference to the sugar glucose.
It is a very toxic element and was named for its chief mineral, beryl, an aluminum beryllium silicate.

ECONOMIC IMPORTANCE
* Beryllium is used in computers, lasers, televisions, oceanographic instruments, and personal body armor.
* Beryllium and its oxide are used as a moderator around the core of a nuclear reactor because of the tendency of beryllium to slow down or capture neutrons.
* Many parts of supersonic aircraft are made of beryllium alloys because of their lightness, stiffness, and dimensional stability.
* It has high tendency to form complexity.
