因此，1232是我们能够得到的,最高的动能，它是从这个轨道中,打出一个电子需要消耗的最低能量。

So in the case of 12 32, that is our highest kinetic energy, it's the smallest amount of energy it takes to pop an electron out of that orbital.

电子是按其能量递增顺序，排布在轨道上的，首先占满第一级，即最低能级。

Electrons will occupy orbitals in order of ascending energy, occupying the lowest energy first and up.

youdao

从最高占据轨道上，去掉一个电子是合理的，因为这样是发射一个电子，所损失的最低能量。

It makes sense that it's going to come out of the highest occupied atomic orbital, because that's going to be the lowest amount of energy that's required to actually eject an electron.

So let's think about shielding in trying to answer why, in fact, it's those s orbitals that are the lowest in energy.

所以我们来考虑一下,尝试回答为什么，事实上s轨道,是能量最低的轨道。

So if we go to the ground state, what you see is we're at that lowest energy level, and we only have one possibility for an orbital, because when n equals 1, that's all we can do.

如果我们在基态上，你可以看到，我们在能量最低的态上，只有一种，可能的轨道，因为n等于1，只有这种可能。
