INTRODUCTION
Strontium is a chemically reactive, malleable, ductile metallic element, and was first isolated in 1808.Its oxide had been known as early as 1790.It ranks about 15th among the elements in natural abundance in Earth's crust.
Strontium was named after Strontian, a town in Scotland.It oxidizes readily upon exposure to air, and reacts with water to produce strontium hydroxide and hydrogen gas.

ECONOMIC IMPORTANCE
* Due to the fact that it emits a brilliant red color when burned in air, strontium is used in the manufacture of fireworks and railroad flares.
* A radioactive isotope of the element, strontium-85, is used in the detection of bone cancer.
