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。 - 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。

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。
