Electrons orbiting the nucleus have a negative charge.

围绕原子核运行的电子带负电荷。

The same sort of thing happens to physical systems at quantum scales, like an electron orbiting in a hydrogen atom.

在量子规模里，同样的事情发生在物理系统上，就像一个电子绕氢原子核运行。

Bohr’s model predicted that electrons orbit at very specific energy levels, which he called orbits.

玻尔的模型预测电子在非常特定的能级运行，他称之为轨道。

An atom consists of negatively charged electrons orbiting a positively charged nucleus at a consistent frequency.

原子由带负电的电子以一致的频率围绕带正电的原子核运行。

These two elements, part of a group called the rare-earth metals, have unusual configurations of electrons orbiting their nuclei, and thus unusually powerful magnetic properties.

在这两种同属稀土金属的元素中，围绕原子核旋转的电子排列方式很不寻常，因此具有异乎寻常的强大磁性能。

From a tiny sphere, to electron orbits, to energy levels and then to the electrons being wave-like charge distributions.

从微小的球体， 到电子轨道，到能级， 再到电子的波状电荷分布。

If you have, you might have noticed that there’s a diagram of an atom, with little electrons orbiting the nucleus.

如果你有，你可能已经注意到有一张原子图， 只有很少的电子围绕原子核运行。

In those basic sketches of atoms, it's usually illustrated that electrons orbit around the nucleus just like our planet orbits the sun.

在这些原子的基本草图中，通常说明电子围绕原子核运行，就像我们的行星围绕太阳运行一样。

And then if we were to draw the electons-- well, I could draw it as a smear, but if we want to kind of visualize it a little better, we could say, OK, there's going to be six electrons orbiting.

然后如果我们要画电子——好吧，我可以把它画成涂片， 但如果我们想更好地形象化它， 我们可以说， 好吧，会有六个电子在轨道上运行。
