Times the square of the elementary Z charge times n squared over Z.

乘以元电荷的平方,乘以n的平方除以。

So the square root of n squared r e over r h.

这里的n值是什么呢？

So, if we just rearrange this equation, what we find is that z effective is equal to n squared times the ionization energy, IE all over the Rydberg constant and the square root of this.

我们可以发现有效的z等于n的平凡，乘以电离能除以里德堡常数,这些所有再开方，所以等于n乘以,除以RH整体的平方根。
