- one of several elements, of the alkaline-earth group; a material having a silver-white color, and melting at a really high heat. It is difficult to search for the pure metal, through the facility with which it becomes oxidized in the air. Atomic fat, 137. Sign, Ba. Its oxide labeled as baryta.
1. A metallic factor of the alkaline earths with an atomic amount of 56 and an atomic weight of 137.34. The symbolization for barium is Ba.2. In medication, refers to a chalky solution of barium used to coat the inside of organs, for instance the stomack or intestines so that they will appear on an x-ray. See additionally: Barium enema; Barium swallow.
1808, coined in Modern Latin by its discoverer, English chemist Sir Humphrey Davy (1778-1829), because it had been present in the mineral barytes "heavy spar" (barium sulphate), so-named by Lavoisier from Greek barys "heavy" (see grave (adj.)). The metal is really fairly light.
