1885年,当门捷列夫描述过的埃卡-硅被发现并命名为锗时,也带来了额外的支持。
Additional support came in 1885 when eka-silicon, which had also been described in advance by Mendeleyev, was discovered and named germanium.
镓表现出的性质与门捷列夫对“铝下元素”的预测密切对应,为周期律提供了有力的支持。
The close correspondence between the observed properties of gallium and Mendeleyev's predictions for eka-aluminum lent strong support to the periodic law.
门捷列夫比迈耶更大胆,他甚至认为,如果测量到的原子质量在表中把一个元素对应于错误的位置,这个原子质量就是错误的。
Mendeleyev was bolder than Meyer and even assumed that if a measured atomic mass put an element in the wrong place in the table, the atomic mass was wrong.
那就是为什么我们要赞美门捷列夫。
