| Some modern colored television contains Strontium too. |
In 1787, an unusual rock which had been found in a lead mine at Strontian, Scotland, which was investigated by Adair Crawford. He realised that it was a new mineral containing an unknown ‘earth’ which he named it Strontia.
In 1791, Thomas Charles Hope, made a fuller investigation of it and proved it was a new element. He also noted that it caused the flame of a candle to burn red.
In 1808, Sir Humphry Davy finally isolated the new element, Strontium.
Atomic Number : 38
Name : Strontium
Latin Name : Strontium
Electrons per shell : [2, 8, 18, 8, 2 ]
Discoverer : Thomas Charles Hope ( 1791)
Isolator : Sir Humphry Davy ( 1808 )
Element's : Atomic Mass : 87.62u
: Density : 2.64g/c㎥
: Type : Alkali Metal
Chemical Properties :
- Reacts vigorously in water
- Quickly tarnishes in air
- Will naturally combined with other elements or compounds that are in the air.
- Naturally occurring Strontium isotopes is stable, but it's another isotopes which is produced by nuclear fallout is called Sr-90.
Physical Properties
- Soft ( Softer than Calcium )
- Silvery - yellow in colour
THIS IS THE END OF STRONTIUM
