It is non-magnetic, holds excellent thermal conductivity and resists attack by concentrated nitric acid.
Beryllium resists oxidation when exposed to air at standard temperature and pressure.
It is found in 30 different minerals of which bertrandite, phenakite, and Beryl are the most important.
Beryllium content in the ground can pass into the plants grown on it when it is in a soluble form.

Beryllium is very hard while the other members of the family are comparatively soft.
Beryllium reacts with oxygen only at very high temperature while the rest of the members combine upon heating.
Beryllium oxide (BeO) is of amphoteric nature.
Compounds of beryllium are mostly covalent because of the high positive charge density on Be²⁺ ion and polarising power.
Except for beryllium the alkaline earth metals react with hydrogen upon heating to form metal hydrides
Beryllium does not liberate hydrogen from dilute acid readily while other alkaline earth metals evolved hydrogen.
Beryllium does not react with water under any conditions while other alkaline earth metals do react upon heating.

Beryllium is used as an alloying agent.
It possesses high strength, non-magnetic properties, better resistance, and dimensionally stable over a significant range of temperature.
Beryllium fused with copper forms alloys which are used in defence and aerospace industries is a typical application of Beryllium.

Aquamarine and emerald are the most precious forms of beryl. Beryl is the mineral form of beryllium aluminium cyclosilicate.
