barium bar·i·um (bâr'ē-əm, bār'-)
A soft alkaline-earth metal used to deoxidize copper. Atomic number 56; atomic weight 137.33; melting point 727°C; boiling point 1,897°C; specific gravity 3.50; valence 2.
A soft, silvery-white metallic element of the alkaline-earth group. It occurs only in combination with other elements, especially in barite. Barium compounds are used in x-raying the digestive system and in making fireworks and white pigments. Atomic number 56; atomic weight 137.33; melting point 725°C; boiling point 1,140°C; specific gravity 3.50; valence 2. See Periodic Table.
