a0 This is equal to a sub nought for a hydrogen atom, and we remember that that's just our Bohr radius, which is . 5 2 9 angstroms.

它等于,我们记得，这就是波尔半径,也就是0，529埃，实际上。

And basically, what that means is you can actually find an electron anywhere going away from the nucleus, a0 but you're most likely to find that you have the highest probability at a distance of a sub nought, or the Bohr radius.

它说明，虽然你可以,在任何地方,找到电子，但在距离为,或者波尔半径的地方,找到电子,的概率最大，我说过。

For the 2 s orbital, at 2 a nought, a0 so it's just 2 times that constant a nought, which is the Bohr radius.

也就是，乘以常数,玻尔半径，对于3s轨道。

And what he came out with when he did some calculations is that there's the radius that he could calculate was equal to this number a sub nought, which is what we call the Bohr radius, and it turns out that the Bohr radius happens to be the radius most probable for a hydrogen atom.

等于这个a0的值,我们叫它波尔半径，而,波尔半径恰好是,最容易，找到电子的地方，我们对波尔模型,不做过多的解释,这是因为。
