In their 1916 papers, both G. N. Lewis and W. Kossel pointed to the electron configurations of these elements as especially stable.
在1916年的论文中,G·N·刘易斯(G . N . Lewis)和W·科塞尔(w .Kossel)都指出,这些原子的电子构型非常稳定。
So, if we took the case of nitrogen, if we add an electron to nitrogen and go to n minus, we find that the change in energy is 7 kilojoules per mole.

And, in fact, it can't even reach n, because then we would have no potential energy at all in our electron, which is not correct.
事实上,它连n都达不到,因为如果那样的话,电子就没有势能了,这是不可能的。
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 this is not even thinking about the other electron shielding, just if we think of the fact, all we need to think about is that the effect of going to a further away n n as we go down the table.
到现在我们甚至还没有考虑,其它电子的屏蔽效果,即使我们要考虑这个因素,我们需要考虑也就是,沿着周期表的某一列往下走,距离会逐渐变远,将起最重要的作用,actually,dominates,这一结果所产生的影响。
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。
