Analysts say it remains to be seen whether the Palestinians' unilateral effort to get a U.N.security endorsement of a Palestinian state will be sustained or is no more than a publicity stunt meant to get Israel to make concessions.

And when we make these comparisons, one thing I want to point out is that we need to keep the constant principle quantum number constant, so we're talking about a certain state, so we could talk about the n equals 2 state, or the n equals 3 state.

当我们做这些比较时，我想指出的一件事是,我们需要保持常量原则,保持量子数是常数，所以我们在讨论一个确定的态时，我们可以谈论n等于2的态，或者n等于3的态。

So we can't actually see any of that, it's too high energy for us to see. So everything we see is going to be where we have the final energy state being n equals 2.

所以我们是看不见它的,它能量太高了，我们能看见的,都是终态等于2的情况。

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。

We knew from Friday, when we talked about energy, that ground state was that n equals 1 value, that was the lowest energy, that was the most stable place for the electron.

So the key word here is that we asked you to identify the third excited state. So, what white is n equal 4 Ok to for the third excited state? 4 OK.

这里的关键的地方是我,要你们找到第三激发态,第三激发态的n等于多少？

Then we would be able to change our equation to make it a little bit more specific and say that delta energy here is equal to energy of n equals 6, minus the energy of the n equals 2 state.

第一激发态，我们就可以把方程,变得更具体一点，能量差,等于n等于6能量，减去n等于2的能量。

So, for example, if we're talking about the n equals 2 state, all of these four orbital descriptions are going to have the same energy.

例如，当我们说n等于2的态，所有这四个轨道的能量,都是相同的。

So, the third excited state, is n equal to 4, because n equals 2 is first excited, 3 is second excited, 4 is third excited state.

因为n等于2是第一激发态,等于3是第二激发态。

This is called the ground state, n equals one.

这被称作基态，n等于1时。

The ionization energy must then be nothing more than, that is the energy to go from the ground state here to n equals infinity, so that would be the energy at state infinity minus the energy of the ground state.

这个电离能一定不会大于，从基态到n为无限大时的能量,而是等于,无限远处的能量减去基态能量。

麻省理工公开课 - 固态化学导论课程节选

So, for example, we could talk about the n equals 2 state, so that's this state here, and it's also what we could call the first excited state. So we have the ground state, and if we excite an electron into the next closest state, we're at the first excited state, or the n equals 2 state.

例如，我们可以考虑n等于2的状态，它在这里，它也被称作是第一激发态,我们有基态，如果我们把一个电子,激发到它最近邻的态,那就是第一激发态，或者n等于2的态。

So, if, for example, we were looking at a hydrogen atom in the case where we have the n equals 1 state, so the electron is in that ground state, the ionization energy, it makes sense, is going to be the difference between the ground state and the energy it takes to be a free electron.

电离氢原子所需要的能量,如果我们看n等于1的情况,电子在基态，那电离能，很合理的就是基态,和自由电子态的能量差。
