Other details:
- Beryllium is a Group 2 (IIA) element
- It is a metal and has a high melting point
- At ordinary temperatures, beryllium resists oxidation in air
- Beryllium compounds are very toxic
- Its ability to scratch glass is probably due to the formation of a thin layer of the oxide
- Aquamarine and emerald are precious forms of the mineral beryl, [Be3Al2(SiO3)6]
- Its chemistry is dominated by its tendency to lose an electron to form Be2+
- As this ion is so small it is highly polarising, to the extent that its compounds are rather covalent
- Its small size means that its complexes tend to be tetrahedral rather than octahedral
- Name: beryllium
- Atomic number: 4
- Relative atomic mass (Ar): 9.012182 (3)
