如果发射成功，印度将成为第三个将卫星送入月球轨道的亚洲国家。

A successful launch will make India the third Asian nation to place a satellite in lunar orbit.

那么我们称它为第三电离能，或者负的束缚能，还是，2，s，轨道的，但现在我们是从正二价硼离子开始的。

So, what we call this is the third ionization energy, or the negative of the binding energy, again of the 2 s orbital, but now it's in boron plus 2 to we're starting with.

第三定律是，椭圆轨道的周期，和距太阳的平均，距离的，立方成比例。

And then his third law was that if you take the orbital period of an ellipse, that is proportional to the third power of the mean distance to the Sun.

And the third fact that we need to keep in mind is that spins remain parallel prior to adding a second electron in any of the orbitals.

第三个事实是我们需要记住在,每个轨道加入第二个电子之前,自旋保持平行。

So we can think of a third case where we have the 3 s orbital, and in the 3 s orbital 0 we see something similar, we start high, we go through zero, where there will now be zero probability density, as we can see in the density plot graph.

第三个例子那就是,3s轨道,在3s轨道里，我们看到类似的现象,开始非常高，然后穿过，这里，概率密度是0，就像你们在概率密度图里看到一样，然后我们到负的。
