Diatomic mean it's di atomic, it's made up of two atoms, and homonuclear means that those two are the same atoms.
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。
-
These are the planks of his model, that matter is composed of atoms that are indivisible and indestructible.

苯环是一个由六个碳原子,和六个氢原子组成的环。
-
According to this theory, the atoms consist of a positively charged nucleus surrounded by a stream of electrons kept together by attractive forces from the nucleus.
根据这个理论，原子由一个带正电荷的核组成,由于来自核的吸引力,电子流围绕在核的周围。
-
We have either single atoms or molecules consisting of small numbers of atoms.

-
And where we had left off was we were going to start one example of thinking about now where we have a heteronuclear diatomic molecules, so two different atoms in terms of forming the molecule.
我们还剩下一个,异核双原子分子的例子没讲,这里组成分子的原子，是不同的。
-
You don't have gas molecules consisting of thousands of atoms.
并没有这样的气体分子,它们是由成千上万的原子组成。
-
So I said that we want to be talking about valence electrons here, so that means if we're talking about, for example, the octet rule for an f f molecule where we have two fluorine atoms, we need to write the valence electrons as dots around them.
我说过我们在这要讨论的是价电子，这就意味着，如果我们要讨论，比如，关于两个氟原子组成的分子的八隅体规则,我们首先需要把价电子画成围绕在它们周围的点。

As we nowadays know, human bodies are made up of atoms.
我们现在知道人的身体是由原子组成的
-
If the very idea of soul that we're working with here under the dualist picture is the soul as an immaterial substance, it's not made of ordinary atomic matter.
如果关于我们正在讨论的,观点是建立在二元论的基础上,即灵魂是非物质实体,它并非由一般的原子物质组成
-
For example, in terms of the atomic theory of matter, at the time at the turn of the Century, the understanding was that atoms were the most basic constituent of matter, meaning you couldn't break atoms up into anything smaller - that was it, you're done.
例如在原子理论中,在19，20世纪之交的时候,人们认为原子是,组成物质的最基本粒子,也就是说你不能,把原子再分割了,就这样了。
-
Again, we're going to take the linear combination of those p atomic orbitals and make what are called pi or some more sigma molecular orbitals.
同样的，我们需要得到,原子p轨道的线性组合,然后组成我们所说的,π分子轨道或者sigma分子轨道。
-
All of these multiatomic moieties are nonpolar.
这些分子由多原子组成，但都是非极性的。
-
And what I'll mention to you just in terms of the fact that -- we're finally dealing with real molecules, which is -- or molecules that are made up of more than one atom, which is kind of exciting for me and maybe for some other of you that like to move into thinking about what some of the consequences of these molecules reacting might be.
而我将要告诉大家的是,我们终于开始与真正的分子打交道了，或者说由多于一个原子所组成的分子，这让我和你们中的某些人感到有些兴奋,因为我们更喜欢思考这些分子,经过反应之后可能出现的一些结果。
-
And then we're going to name the atomic orbitals that make it up, and it's being made up of a carbon 2 s p 3 orbital, and a hydrogen 1 s orbital.
