So, I've got this tiny volume with, in the case of gold 79 plus of charge, and I've got some electrons out here somewhere, and the vast majority of the atom is nothing.
我认为这个小体积里面,比如金的79个正电荷,电子在外面的某些地方,原子里面大部分是空心的。
But I want you to tell me in terms of thinking about formal charge, which Lewis structure would you predict to be the most stable?
但我想让大家告诉我,从形式电荷的角度考虑,你会预测哪一个路易斯结构是最稳定的?
So, I've got plus twos, zooming in at high energy against a wall of positive charge.
两个高能的正电荷,在正电荷壁垒时会遇到阻力。
I don't mean they dig in the ground, but they supervise it; they think about it. They are like people who are in charge of a plantation, their own plantation,I mean.
他们亲自开垦土地,但是他们亲自监督,他们出谋划策,他们就像是,自己种植园的负责人
In fact, the three justices, the three judges, who were in charge of the judicial trial of Charles I, King Charles, the one who lost his head, those three judges later found a home where?
实际上,那三个法官,主持了查理一世审判的法官,查理一世丢了头,这三个法官后来在?
Often a good thing to start with is to put the lowest ionization energy atom in the middle, and if you don't have charge separation then go with that structure, but if you do find you have a lot of separation, such as the case in negative 2, positive 2, and minus 1, then you want to say wait a second, this is really bad in terms of formal charge, let me go ahead and see what other options I have here.
通常一开始把电离能最低的原子,放在中心位置就很好了,如果你发现电荷没有分开,那么这个结构就没问题了,但是如果你发现有很多分开的电荷,比如这种情况,有负二,正二和负一,那么你会想要说等一下,从形式电荷来看这很不好,让我去看看其它可能的选择。
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。
