单词 thorina
释义

thorinan.

/θɒˈrʌɪnə/
Etymology: < French thorine, 1817, a bad representation of Berzelius's name Thorjord , German Thorerde : see thoria n.In the Annales de Chemie, etc. 1817, V. 5, the form thorine is erroneously attributed to Berzelius himself (‘une nouvelle terre à laquelle M. Berzelius a donné le nome de thorine’). Misled by this, English chemists long used thorina and thorinum for thoria and thorium.
Chemistry. Obsolete.
1. The name given at first to a substance found by Berzelius in 1815 in various Swedish and Norwegian minerals, and named by him Thorjord, which afterwards proved to be yttrium phosphate.
