[barium etymology, barium origin, 英语词源] - barium (n.)
- 1808, coined in Modern Latin by its discoverer, English chemist Sir Humphrey Davy (1778-1829), because it was present in the mineral barytes "heavy spar" (barium sulphate), so named by Lavoisier from Greek barys "heavy," from PIE root *gwere- (2) "heavy" (see grave (adj.)). The metal is actually relatively light.
