Essential Facts about Strontium

1. Strontium is a soft, silvery-white metal that belongs to the alkaline earth metals group on the periodic table.
2. The element has an atomic number of 38 and the chemical symbol Sr.
3. Like calcium, strontium readily oxidizes when exposed to air, turning a yellowish color.
4. The element was discovered in 1790 by Adair Crawford and William Cruickshank in a Scottish mineral.
5. Strontium is named after Strontian, a small village in Scotland where the mineral strontianite was first found.
6. At room temperature, pure strontium is slightly softer than calcium and can be cut with a knife.
7. The element exists in four stable isotopes in nature: strontium-84, strontium-86, strontium-87, and strontium-88.
8. Pure strontium must be stored under kerosene or mineral oil to prevent oxidation.
9. The metal reacts vigorously with water, similar to how sodium fizzes on water’s surface.
10. When burned, strontium produces a distinctive bright red flame, making it perfect for fireworks.
