neutron number

常见例句

The number of neutrons in an atom, the neutron number, is given by the quantity A-Z .
这个术语指的是，纯元素的原子与所有的物质单一类型。
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。
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。

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。
