I won't be far away.

VOA: standard.other

How far you are away from the nucleus in terms of a radius, they don't depend at all on those two angles, theta they're independent of theta phi and they're independent of phi.

只和离核子的距离，也就是半径有关，它们和,另外两个角度无关，它们不决定于,也不决定于。

What I just spent many lectures discussing is the fact that we can not know how far away an electron is from the nucleus, so we can't actually know the radius of a certain atom.

我花了这么多课时所讨论的正是我们,不可能知道电子离原子核有多远这一事实，因此我们不可能知道某个原子的半径。

In other words, if you look too closely at a picture or if you stand too far away from it you don't see it clearly it's out of focus but if you achieve just the right distance from it, it comes into focus.

换句话说，如果你站得离一幅图画太近,或太远都无法看清它,它在焦距之外,但是如果你站在合适的位置上，焦距就对准了，画就清晰了。

Keep in mind we do have this p orbital here and it's coming right out at us. And this p orbital is here, but it's empty, it doesn't have any electrons in it, that's why we don't have to worry about it in terms of getting our electrons as far away from each other as possible.

他们程120度角互相远离,这样它们离得最远，记住我们这里确实有个p轨道，它朝向我们，这里有个p轨道，但它是空的,里面没有电子,这就是为什么我们在考虑。
