他写道：“毕竟，移动电子比移动原子更有效率。”

"After all," he wrote, "It's much more efficient to move electrons than to move atoms."

那么，我们看到两个分开的氢原子所具有的能量,比原子中没有电子时更低。

So, we see that the two h atoms separate have a certain energy that's lower than when the electron's not with the atom.

这就解释了为什么我们不担心，原子核运动起来，因为原子核和电子的质量比约为2000 ？

That is why we don't worry about the motion of the nucleus 1 because the ratio of mass is about 2,000 to one.

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。

So, we're going to start with talking about bonding, and any time we have a chemical bond, basically what we're talking about is having two atoms where the arrangement of their nuclei and their electrons are such that the bonded atoms results in a lower energythan for the separate atoms.

那么，下面我们将从成键开始讲起，无论什么时候我们有一个化学键，基本上我们所讨论的,都是如何安排两个原子的原子核的位置,与电子的位置使得成键的两个原子,最终比分开时的能量更低。
