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.
好的,这是一个关于使用元素周期律的反例。
All right. So that is an anti-example of using periodic trends.
本文对周期律的“不规则性”及其理论阐释进行了探讨。
In this paper, the "Irregularity" and Its theoretical interpretation for periodic table have been discussed.
So, let's just take a quick example to show how not completely you can use these periodic trends, that there are limits.
那么,让我们举一个小例子来看一下,你是如何不能将元素周期律用在所有地方的,它是有局限性的。
But you actually need to keep a few caveats in mind as you do this, which is the fact that trends predict a lot of chemical properties, but they can't predict everything in terms of biological properties.
不过在你使用的过程中,需要牢记一些注意事项,那就是元素周期律可以预言很多化学性质,但是不能预言一切性质,比如生物学性质。
So anyway, when we talk about periodic trends, it doesn't always match up.
无论如何,当我们讨论元素周期律时,要知道它并不是总能与实际情况相符。
