At some point, you will cut the magnet so small that you will have cut down to the size of a single atom.

从某个方面看，你会把磁体切到如此之小，小到只有一个单原子那么大。

These are all one electron atoms, and they are gas, a single atom.

这些都是单电子原子，它们都是气体，都是单原子。

Even molecules that differ by a single atom can vibrate quite differently.

即使只相差一个原子的分子也会有差别很大的振动。

Whereas in molecular orbital theory, what I'm telling you is instead we understand that the electrons are spread all over the molecule, they're not just associated with a single atom or a single bond.

而在分子轨道理论里，我要告诉你们的时,我们任为电子分布在整个分子中,它们不仅仅是和,一个原子或者一个键有关。

So let's go to a second clicker question here and try one more. So why don't you tell me how many possible orbitals you can have in a single atom that have the following two quantum numbers?

让我们来看下一道题目,你们来告诉我,有多少个可能的轨道,含有这些量子数呢？

FORBES: The Story Of Eau

This let researchers see objects as small as 1 nanometer in size--about five times larger than a single atom.

FORBES: Stealth Visionary

The idea was to get one of each type of atom to stick together to become a single atom of element 118.
