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。

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。
