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。
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。
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。
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。
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。
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。
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。
But the neutrons, it doesn't matter about the neutrons.
但是它并不影响到中子。
So, this has got protons and neutrons.
这里面有质子和中子。
This is sum of protons plus neutrons.
它是质子数加上中子数。
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。
