From the existence or non-existence of an atomic fact we cannot infer the existence or non-existence of another.

从一个原子事实的存在或不存在中，我们不能推断出另一个原子事实的存在或不存在。

In logic, nothing is accidental: if a thing can occur in an atomic fact the possibility of that atomic fact must already be prejudged in the thing.

在逻辑中没有偶然的事情：如果一个事物能够出现在原子事实中，那么这个原子事实的可能性必定早已包含于该事物之中。

In the atomic fact the objects are combined in a definite way.

在原子事实中，对象之间以某种确定的方式相连。

I would say with the aid of an energy level diagram explain the fact that helium is found as atomic gas and not molecular. How about this one?

我要说的是，在能级图的帮助下,可以解释氦气是单原子气体,而不是分子气体这一事实,那么这个呢？

The 1 s just comes from the fact that the molecular orbital is a combination of two 1 s atomic orbitals.

是因为分子轨道是两个,1s原子轨道的组合。

But once we got to the atomic size scale, what happens is we need to be taking into account the fact that matter has these wave-like properties, and we'll learn more about that later, but essentially classical mechanics does not take that into account at all.

但一到到了原子尺度量级，我们必须考虑到物质,这时候有波动性质,关于这点我们今后将会学到更多,但本质上经典力学并,没有考虑这个性质。

But the fact that the molecules can be made and seen confirms long-held fundamental atomic theories.
