neutron number中文翻譯:
n.核內中子數
neutron star───n.[天]中子星;n.中子星
number───vi.計入;總數達到;vt.編號;計入;數…的數目;使為數有限;n.數;(雜志等的)期;號碼;數字;算術
roll number───磁帶卷號;輥軋號數
cattery number───家畜數

verification number───驗證號碼

school number───學校編號
flat number───公寓號
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。
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。
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。
