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猜想的正确性用了数十年的,因此建立了周期表——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.
看看周期表,那些非常想给出电子的——我之前已经讨论过这一点了——是碱金属。
