Classification of the element

 Classification of element into metal and non-metal:  Metal

Other elements present in the group towhich the element belongs:                                                      Beryllium 

Magnesium 

Calcium 

Barium

Radium

State of compound from which element is extracted: Solid

Half life of the element: 28.9-year

Radioactive strontium is much more of a health risk than stable strontium.   When the uptake is very high, it may cause anaemia and oxygen shortages, and at extremely high concentrations it is even known to cause cancer as a result of damage to the genetic materials in cells.

What is the property of the element which makes it useful in a particular field?

Although strontium-90 is a dangerously radioactive isotope, it is a useful by- product of nuclear reactors from whoose spent fuel is extracted. Its high-energy radiation can be used to generate an electric current, and for this reason it can be used in space vehicles, remote weather stations and navigation buoys.

Properties: Strontium is a silvery-white, shiny metal. When exposed to air, it combines with oxygen to form a thin film of strontium oxide (SrO). The film gives the metal a yellowish color. Strontium has a melting point of about 757°C (1,395°F) and a boiling point of 1,366°C (2,491°F).

Strontium is best known for the brilliant reds its salts give to fireworks and flares. It is also used in producing ferrite magnets and refining zinc. Modern 'glow-in-the-dark' paints and plastics contain strontium aluminate
