But it is interesting. Let's just, for an order of magnitude say what happens for ground state electron in atomic hydrogen?
但行星模型其实挺有趣的，按照重要的先后顺序，我们来猜想一下,氢原子中的基态电子会发生些什么？
-
So we saw that our lowest, 1 0 0 our ground state wave function is 1, 0, 0.
我们看到最低的，或者基态波函数是。
-
In other words, just want to know where the electron is somewhere within the shell radius of the ground state of atomic hydrogen anywhere.
换言之，我只是想知道,电子在哪,可以在氢原子基态下的半径,里面的任何地方。
-
Now, if this incident energy is great enough it will take an electron out of the ground state and promote it.
现在，如果入射能足够的话,它会将一个电子从基态中释放出来,并且加速它。
-
We're always talking about the ground state unless 1 we specify that we're talking about an excited state.
我们指定说讨论激发态,而且对于电子。
-
Well, the energy at infinity is zero -K and the energy in the ground state is minus K.
无限远处的能量值为,而基态能量值为。
-
It is the value of the radius of the ground state electron orbit in atomic hydrogen.
它就代表氢原子基态电子,的轨道半径。
-
So, we can think about what is it that we would call the ground state wave function.
我们来考虑一下,基态的波函数，是怎么样的。
-
We know how to write that in terms of the state numbers, 1 0 0 so it would be 1, 0, 0, because we're talking about the ground state.
我们知道如何去,写出态数字，它是，因为我们在讨论基态,我们总是讨论基态除非。
-
So this is our complete description of the ground state wave function.
所以这是我们,对基态波函数的完整描述。
-
So what you can see is again, we've got this ground state.
你们可以看到，这是基态。
-
s And this is the ground state, n equals one.
这是最低能级。
-
So, if we're talking about five different orbitals and we're talking about a ground state atom, we know that we just need to start at the bottom and work our way out up.
因此，如果我们要讨论的是,五个不同的轨道且是属于一个基态原子的话，我们知道，我们只需要从最低的轨道,开始一个一个往上找。
-
What is the binding energy of the ground state electron in hydrogen?
氢在基态的情况下,它的电子结合能是多少？
-
And this lowest orbit is termed the ground state.
这个最低轨道被称作基态。
-
That is the ground state energy of atomic hydrogen.
同时也是氢原子基态的能量值。
-
Suppose the E incident is greater than the energy in the transition going from ground state n=2 What will happen?
假设入射能量远远大于,从基态向,转变的能量。，to，n，equals，two。,那会发生什么？
-
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.
我们上周五知道了，在讨论能量的时候，基态指，n等于1的态，它能量最低，是，最稳定的态。
-
So we are going to put atomic hydrogen Z equals one, 1 ground state n equals one.
氢原子Z等于，基态n也等于。
-
It is telling us that the ground state in lithium would be Z squared.
它告诉我们锂原子的基态,是z的平方。
-
If you look at the ground state in two different systems -If you look at the ground state which is n equals one, think about this, if I increase the proton charge, the Coulombic force of attraction is greater.
如果你观察两个不同系统的基态,当你观察n，等于1的基态时，试想一下，如果我增加质子电荷，相互吸引的库仑力就会更大。
-
So if we go to the ground state, what you see is we're at that lowest energy level, and we only have one possibility for an orbital, because when n equals 1, that's all we can do.
如果我们在基态上，你可以看到，我们在能量最低的态上，只有一种，可能的轨道，因为n等于1，只有这种可能。
-
l But now we need to talk about l and m as well. So now when we talk about a ground state in terms of wave function, we need to talk about the wave function of 1, 0, 0, and again, as a function of r, theta and phi.
但我们现在需要讨论,和m，现在当我们讨论,波函数的基态时，我们讨论的，是1，0，0的波函数，同样的，它也是r，theta和phi的函数。
-
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。
