You are allowed to use on the test the official version of the Periodic Table of the Elements which most of you should have by now.
在测试中你们可以使用,化学元素周期表的官方版本,你们应该大部分都有了吧。
Remember, all you have to do is fill in the one or two-letter abbreviation for the chemical symbol.
记住,你们只要,用一两个字母的缩写,来代表化学元素就可以了。
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。
If you take some from column one or two and you mix it with some from column eight and nine, bingo, you have reaction.
如果你从第一列或者第二列中选出一些元素,将其与第8列或者第9列的元素混合,好,就会发生化学反应。
You are required only to put the one or two-letter chemical abbreviation, the symbol.
你们只需要,用一两个字母来代表一个化学元素。
And what he did what he actually grouped things in terms of their chemical properties.
他所做的,实际上他是根据元素的化学性质,来对它们进行归类的。
And this will have to go up before The International Union of Pure and Applied Chemistry before they approve it because they fought over element 106 for the longest time, but I think this will go through fairly quickly.
但还是要往上申请,直到国际纯粹与应用化学联合会,因为同意,他们为106号元素抗争了很久,但我想这个应该会很快通过。
Atoms of different elements have different weights and different chemical properties.
不同元素的原子的质量不同,化学特性也不相同。
The thesis of 3.091, and this is where the chemistry comes in, is that electronic structure of the elements holds the key to the understanding, not just the chemical bonding, but the long range atomic order.
这是这门课的论点,这是化学的研究点,也就是元素的电子结构,那即是理解的关键,不只是化学键,还有长程的原子排序。
