The periodic table is an arrangement of the elements in order of increasing atomic number. Elements that exhibit similar chemistry appear in vertical columns called groups (numbered 1–18 from left to right); the seven horizontal rows are called periods. Some of the groups have widely used common names, including the alkali metals (group 1 ...

STRONTIUM. Strontium was discovered by Adair Crawford (GB) in 1789. Named after the village of Strontian in Scotland. It is a soft, malleable, silvery-yellow metal that is combustible in air and reacts with water. Exposed surfaces form protective oxide film. It ignites and burns readily. Strontium is found in minerals celestite and strontianite.

Periodic Table--Strontium. The alkali earth metal strontium has four stable, naturally occurring isotopes: 84 Sr (0.56%), 86 Sr (9.86%), 81 Sr (7.0%) and 88 Sr (82.58%). Only 87 Sr is radiogenic; it is produced by decay from the radioactive alkali metal 87 Rb, which has a half-life of 48,800,000 years. Thus, there are two sources of 87 Sr in any material: that …
