The electronic configuration, all it is is the shorthand notation for that one electron approximation for the Schrodinger equation for lithium.

电子构型就是，对于锂的薛定谔方程,的单电子近似的,简化形式。

So, for example, if we're to hold the time constant, this makes it a lot simpler of an equation, because what we can end up doing is actually crossing out this whole term here.

比如说，如果我们把时间,定为常数，这使得方程,大大简化，因为我们可以把,这一项划掉。

And thanks to our equation simplified here, it's very easy for us to figure out what actually the allowed energy levels are.

由于有了简化的方程，我们很容易看出,这些允许的能级在那里。

So now we have that energy is equal to the negative of the Rydberg constant divided by n squared.

我们可以把能量方程大大简化,现在能量等于负的Rydberg常数除以n平方。
