鉫五行属什么？
“镓”是一个中国古代就发现的元素，其化学性质与铝、锗相似——所以中国人早就猜想到了它是什么，只是由于无法分离出单质而无法确认罢了（因为中国当时还没有发明金属冶炼法）；
15 years ago， the English chemist H. C. Brown and his co-workers extracted a gas from uranium ore that they called “gallium，” which they postulated was probably an element distinct from gallium salts， such as gallium arsenide， known to exist at this time; 20 years later scientists confirmed their hunch by isolating gallium in quantity from its ores． The name is often spelled without the final letter “e”—as in the present article—because it resembles Latin word for “joyful，” gaudia. This spelling has been recommended since about 1979， but some authorities still recommend Gallium (including Webster’s Ninth New Collegiate Dictionary) because of older associations. I will use both forms interchangeably here， though most references will favor one or the other. It should be noted however that when dealing with historical usage there are two types of Gallium/Gallium： One refers to the elements and the other denotes the compound gallium arsenide. For reasons not relevant to my discussion these compounds were traditionally named after Latin words for joy rather than the corresponding elements themselves， hence the traditional spelling. Because of this distinction， the modern spelling would not have helped if we needed to distinguish between the element and its compounds before the late seventies！
The chemical symbol for gallium comes directly from ancient Greek， derived via Latin from the same root verb that produced the English terms “galaxy，” meaning “milky way，” and galeous， meaning “salty.” As mentioned above， while early writers on chemistry used the term “gallium” consistently to refer to whatever the new substance turned out to be， others preferred more descriptive names like “newly discovered rare metal，” etc… Since the eighteenth century， many different spellings have been applied to this chemical symbol， including Galix， Gailleum， Gaellium， Galeam， Galaum等……and even occasionally Gallium itself. However， according to CIP Guide， only the version with double l’s should now be recognized officially： [Ga] … There seems to be no consensus yet regarding how best to render this symbol phonetically into English， although most
