当化学在西方兴起后,只是到了18世纪后半期拉瓦锡根据精确的实验,证明燃烧是可燃物与氧气化合所构成的过程,这样就彻底地推翻了燃素学说,化学乃因之开始成为一门严谨的科学。拉瓦锡的功绩并不止此。当他得到另外三位化学家的协助,并于1787年公布了为化学物质命名的法则。这些法则具有高度而合理的系统性。 依这些法则,凡元素都用一个单字标志,而化合物不计其为二元或多元,其命名都系统地用二个分立的单字构成,金属元素的名字总放在前。钠和氯可构成化合物,今以
When chemistry emerged in the West, it was only by the second half of the 18th century that Ravassah, on the basis of precise experiments, proved that combustion was the process of combustibles and oxygenation, thus completely overturning the phlogiston theory that chemistry began to become one Door rigorous science. Raval’s merit is more than that. When he was assisted by three other chemists, and in 1787 published the rules for naming chemicals. These rules are highly and reasonably systematic. According to these rules, all the elements are marked with a single word, and the compound does not count as binary or plural. The names of the compounds are systematically composed of two separate words, and the names of the metal elements always precede. Sodium and chlorine can form compounds now
