Group one, if you put hydrogen aside, these are referred to as the alkali metals.

第一族，如果你把氢排除在外，这些元素被称为碱金属。

It took decades to tease out the truth of Debereiner's conjecture, and thus to construct the periodic table-in which the alkali metals form the first column.

科家证实Debereiner猜想的正了数十年的时间，也因此建立了元素周期表——碱金属组成了第一族。

Well if you look at the period table, the people who want to give really badly-- and we've talked about this a good bit-- are the alkali metals.

看看元素周期表，那些非常想给出电子的元素——我之前已讨论过这一点了——是碱金属。
