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."

电子比原子核小得多，并不任意乱飞，而是贴着固定的轨道飞行。

The electrons, much smaller than the nucleus, don't fly around at random but stick to fixed orbits.

One of the main difference is is that when you're talking about multi-electron orbitals, they're actually smaller than the corresponding orbital for the hydrogen atom.

其中最主要的区别之一,是当你讨论多电子轨道时,它们实际上，要比对应的氢原子轨道,要小一些。
