Strontium is a Alkaline earth metal in group 2. It has a Face centered cubic crystalline structure. This element has 4 stable isotopes: 84, 86, 87, and 88.

Strontium is indistinguishable from Calcium to cells, and radioactive strontium 90 is often found in bones of humans and other animals after nuclear detonations.
