常見例句雙語例句The number of neutrons in an atom, the neutron number, is given by the quantity A-Z .這個術語指的是,純元素的原子與所有的物質單一類型。This means you can vary the neutron number without changing chemical identity, because chemical identity is fixed by the proton.這表示你可以改變中子數,而不會改變它的化學特性,因為化學特性是由質子決定的。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,我們知道它有質子數,根據定義,那就是6,而電子數,12減6等于6,所以它有6個中子。原聲例句This means you can vary the neutron number without changing chemical identity, because chemical identity is fixed by the proton.這表示你可以改變中子數,而不會改變它的化學特性,因為化學特性是由質子決定的。麻省理工公開課 - 固態(tài)化學導論課程節(jié)選Now the last thing is that because the neutron has no net charge, we can change neutron number.現在,最后一件事是,因為中子沒有凈電子,我們可以改變中子數。麻省理工公開課 - 固態(tài)化學導論課程節(jié)選So carbon 12.
