All four of these orbitals have the same energy, t hey're degenerate.
这四个轨道,能量相同,是简并的。
-
That's what we call degenerate orbitals, they're the same energy.
我们称之为简并轨道，它们具有相同的能量。
-
Degeneracy is where you have orbitals of equivalent energy.
简并发生在轨道能量相同的地方。
-
When we talk about the n equals 2 state, we now have 2 squared or 4 degenerate same energy orbitals, and those are the 2 s orbital.
当考虑n等于2的态时，我们有2的平方,或者4个简并能量的轨道，它们是2s轨道。
-
Remember we have to put one in each degenerate orbital before we double up on any orbital, so just keep that rule in mind that we would fill one in each p orbital before we a to the second one.
我们必须把,每一个放入简并的轨道,我们把每一个电子放在p轨道里，所以把规则记在脑子里,我们把每一个电子放在p轨道里,在我们放入第二个电子之前。
-
And the word degenerate simply means same energy, are of equal energy when they're degenerate.
简并“一词指的是，能量相同，你有n平方个等能轨道，是简并的。
-
So that's the 1 s orbital - we have n squared or 1 degenerate orbitals.
所以这是1s轨道,我们有n平方,或者1个简并轨道。
-
But these three p orbitals are degenerate.
但这三个p轨道是简并的。
-
And we can generalize to figure out, based on any principle quantum number n, how many orbitals we have of the same energy, n and what we can say is that for any shell n, there are n squared degenerate orbitals.
我们可以总结出来，在，主量子数为n的情况下，同一个能量上，有多少个轨道，我们可以说，对任何壳层，有n平方个简并轨道。
