So today, we're going to start talking about the hydrogen atom.

今天我们将谈到氢原子。

All right. So today we're going to finish up our discussion of the hydrogen atom.

好，今天我们要结束，关于氢原子问题的讨论。

In cases you're extremely familiar with, if it were the hydrogen atom, it would be down in the 1s orbital.

对于你们所熟悉，的氢原子，就是1s轨道能级。

Hydroxyl is the combination of one hydrogen atom and one oxygen atom.

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。

All right. So, let's pick up where we left off, first of all we're still on the hydrogen atom from Monday.

好，让我们从上次停下的地方讲起，我们还要讲周一讲的氢原子。

The researchers caught an intermediate step in the process by which hydrogen is removed from tryptamine, namely the point at which a proton disappears from a carbon atom as the carbon-hydrogen bond breaks.

Hydrogen, the simplest atom, consists of a single proton encircled by a single electron.

The nebulous field of nanotechnology, freighted with as much hype as legitimate promise, boils down to the process of manipulating matter on a molecular scale (a nanometer is one billionth of a meter, about ten times the width of a hydrogen atom).
