There are some exceptions, which we'll get to later, but the only a big exception here is with hydrogen, which has a special stability that's associated with two electrons.

但也有一些例外我们将以后再讲，但这里只有一个较大的例外，氢，它的稳定性比较特殊，只需要两个电子。

So the open curly brace followed by the closed curly brace means everything inside of these curly braces should get executed, but only if that first condition is actually true.

所以左花括号后面跟着,右花括号，这意味着花括号里面所有的代码,都应该是要被执行的，但只有当第一个条件是正确的。

We're going to get to more complicated atoms eventually where we're going to have more than one electron in it, but when we're talking about a single electron atom, we know that the binding energy is equal to the negative of the Rydberg constant over n squared, so it's only depends on n.

我们以后会讲到，更加复杂的情况,那时候,不只有一个原子，但当我们讲，单个原子的时候，我们知道结合能，等于,负的Rydberg常数,除以n平方，所以它仅仅由n决定的。
