这是同核分子所以是非极性的。

This is homonuclear and so these are nonpolar.

而是用的同核，嗯，这是完全共价的。

They say homonuclear. So this is purely covalent.

双原子意味着它是两个原子，它由两个原子组成，同核意味着这两个原子时相同的原子。

Diatomic mean it's di atomic, it's made up of two atoms, and homonuclear means that those two are the same atoms.

So where we had left off with was we'd fully discussed up to the point of considering homonuclear diatomic molecules, so molecules that both have the same nucleus.

我们上次,讲到了我们,已经讨论过同核双原子分子，也就是有相同原子和的分子。

This is purely covalent because all it is is homonuclear bond energies.

是一个完全的共价成分,他的理由是他们都是同核共价。
