Be - Beryllium - ALKALINE EARTH METAL

Beryllium, symbol Be, is a chemical element with atomic number 4. Its name comes from the Greek word meaning crystal. It is a steel gray metal, it is light but resistant, fragile and toxic. In nature, it is mainly found in the form of oxides or aluminosilicates such as aquamarine or emerald. Beryllium is used in alloys as a hardening agent
