So we say if n increases, the orbital size is also going to increase.

轨道的尺寸，也增大了。

So if we're keeping n the same, we look and what we saw was that size actually decreases as we increase the value of l.

如果我们保持ｎ不变，我们看到随着ｌ值的,增大尺寸变小。

If you look at the ground state in two different systems -If you look at the ground state which is n equals one, think about this, if I increase the proton charge, the Coulombic force of attraction is greater.

如果你观察两个不同系统的基态,当你观察n，等于1的基态时，试想一下，如果我增加质子电荷，相互吸引的库仑力就会更大。

This should make sense to you, because they don't, in fact, want to gain another electron, because that would mean that electron would have to go into a new value of n, a new shell, and that's really going to increase the energy of the system.

这对大家来说应该容易理解，因为它们实际上不想得到另一个电子，因为这意味着这个电子不得不,到一个新的，n，值更大的壳层上去，这将会增加系统的能量。
