About electrons as music, and electron shells and the orbitals they contain.

关于作为音乐的电子， 以及电子壳和它们包含的轨道。

The second electron shell is physically larger and thus can include more than just the s-orbital.

第二个电子壳在物理上更大， 因此可以包含的不仅仅是 s 轨道。

The structures of the electron shells surrounding the nuclei of their atoms are complicated, meaning they are chemically versatile. This is what makes them good catalysts.

它们原子核周围的电子壳层的结构很复杂，这意味着它们具有多种化学用途。这就是它们成为良好催化剂的原因。

Oxygen itself is super needy, with two vacancies in its outer electron shell that it would just LOVE to fill up.

氧气本身非常需要，它的外层电子壳中有两个空位，它很想填补。

Now there are a couple of elements that have weird electron shells, but you can just look it up on Google.

现在有一些元素有奇怪的电子层， 但你可以在谷歌上查一下。

Chemical reactions happen when an atom's outermost electrons do stuff, and the protons and neutrons and even the inner electron shells are usually completely unaffected.

当原子的最外层电子做事时就会发生化学反应，而质子和中子甚至内层电子壳层通常完全不受影响。
