The electrons are not equally shared and the carbon hogs the electrons a little bit more than the hydrogen, so the carbon is electron-rich and the hydrogen is just a little bit electron-deficient.

电子不是平均共享的,碳原子比氢原子吸引电子,更强烈一点点，所以碳原子是富电子,而氢原子是缺电子。

The negative ions, these are electron-rich.

二负离子，它们有富裕的电子。

And then we said you can also achieve octet stability and electron transfer if you look at elements that are just a little bit rich of electrons versus octet stability or a little bit lean of electrons.

然后我们说你还能达到8电子稳态,以及电子的转移,如果你看看,那些电子较多的元素,违背8偶律，或者有一点缺电子。

We give you a very rich table of constants that's got all kinds of things from the mass of the electron to the speed of light, and all this stuff to the requisite number of significant figures. And, in addition, you are allowed to take in one sheet of paper, 8 1/2 x 11 one sheet 8 1/2 x 11, you can write anything you want on it.

我们会给你一个很详实的常量表,将会涉及很多方面，从元素的电子,到光速，这些内容到有效数字的定量,还有，你们可以带来一张纸，纸的规格是，可以写任何你们想写的东西。
