Then it undergoes a reorganization in which the vice neutrons, assistants to the neutron, the assistants to the vice neutrons exchange places.
而开始重组,其中,副中子,辅助中子,辅助副中子,开始交换位置。
It has 125 assistants to the neutron, it has 75 vice neutrons and 111 assistants to the vice neutrons.
周围有125个辅助中子,有75个副中子和,111个辅助副中子。
Nowadays we know if you go into the neutron or the proton, there are quarks.
如今我们知道,如果进入中子或者质子内部,就会发现夸克
Now, to get to the number of neutrons, what we do is go up here to the upper left.
现在,看看中子数,我们要做的,是看到这左上方。
This means you can vary the neutron number without changing chemical identity, because chemical identity is fixed by the proton.
这表示你可以改变中子数,而不会改变它的化学特性,因为化学特性是由质子决定的。
Now the last thing is that because the neutron has no net charge, we can change neutron number.
现在,最后一件事是,因为中子没有净电子,我们可以改变中子数。
So carbon 12. We know that it has the proton number, by definition, is 6. And the neutron number, 6 from 12 is 6. So it has 6 protons and 6 neutrons.
所以碳12,我们知道它有质子数,根据定义,那就是6,而电子数,12减6等于6,所以它有6个中子。
OK. Neutron walks into a bar and sits down at the bar.
中子走进一个进酒吧,坐在吧台。
And since we don't have to charge compensate, we can add or subtract neutrons at liberty.
因为我们没有电荷补偿,我们就可以随意地加上火减少中子。
And, if the conditions are right, they will combine, fuse and form darmstadtium plus neutron.
如果条件是正确的,它们将会结合,融合并形成鐽中子。
And it is equal to the sum of the number of protons plus the number of neutrons.
它等于质子数,加上中子数。
And carbon 14, 6 again and it has 8, and it is found in vanishingly small amounts, 10 10 to the minus 12 or part per trillion.
碳14,6个质子,8个中子,它的存在是非常微小的,几乎趋于零,万亿分之。
So we get at the number of neutrons indirectly because we know the proton number here.
所以,我们可以间接得到中子数,因为我们知道质子数了。
And then there is this third species, the neutron, which has no charge.
这是第三种了,中子,不带电。
It axiomatically must be 6 protons, and it has 7 neutrons.
它自然也是6个质子,有7个中子。
So, all that's left is the helium nucleus, two protons, two neutrons.
仅留下氦核,两个质子,两个中子。
You're a neutron. He says, yeah, yeah, I'm a neutron.
你是中子,他说,是是,我是中子。
However, it does have one neutron.
但是,它有一个中子。
So, this has got protons and neutrons.
这里面有质子和中子。
But the neutrons, it doesn't matter about the neutrons.
但是它并不影响到中子。
Neutron has no charge.
中子不带电。
We could do it with a neutron.
我们可以用中子来做。
This is sum of protons plus neutrons.
它是质子数加上中子数。
Neutron is kind of quiet.
中子安静了下来。
He didn't shoot neutrals.
他并没有入射中子。
They all have the same Z, the same proton number, but different A, which means number of neutrons varies.
有相同的Z,相同的质子数,但是不同的A,也就是中子数不同。
