That energy will be absorbed by the hydrogen atom, n=1 the electron will rise from n equals one n=2 to n equals two.

这能量将会被氢原子吸收，这个电子会从,上升到。

So another way to say that is, in a sense, if we're thinking about the excited state of a hydrogen atom, the first excited state, or the n equals 2 state, what we're saying is that it's actually bigger than the ground state, or the 1 s state of a hydrogen atom.

换句话说，如果我们激发一个氢原子，第一激发态或者说ｎ等于２的态，我们说它比氢原子基态,或者说１ｓ态要大。

And I want to really highlight here we're talking about for a hydrogen atom orbitals - with the same n value have the same energy.

我想强调的是,我们所说的,都是对单个的氢原子,和言的,对于同样的n值能量相同。
