strontium

[strŏn′chē-əm, -tē-əm]

A soft, silvery metallic element of the alkaline-earth group that occurs naturally only as a sulfate or carbonate. One of its isotopes is used in the radiometric dating of rocks. Because strontium salts burn with a red flame, they are used to make fireworks and signal flares. Atomic number 38; atomic weight 87.62; melting point 777°C; boiling point 1,382°C; specific gravity 2.54; valence 2. See Periodic Table.
