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

第一族，如果你把氢外，这些素被称为碱金属。

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.

科学家证实Debereiner猜想的正确性用数十年的时间，也因此建素周期表——碱金属组成第一族。

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.

看看素周期表，那些非常想给出电子的素——我之前已经讨论过这一点——是碱金属。
