Notes
Strontium is an ingredient in red signal flares. It has a silvery lustre but
oxidizes quickly to turn yellow.To prevent oxidation it is stored in kerosene.
It is ductile and mallable and can easily conduct current. Strontium-90 is
considered the most dangerous constite of radioactive fallout. The heat it
radioactive strontium emits due to radioactive decay can be used to generate
small amounts of electricity. When finely divided it spontaneously ignites
in the presence of air.
