But sometimes a cosmic ray will collide with a nitrogen atom, giving it an extra neutron.

但有时宇宙射线会撞击氮原子，赋予它一个额外的中子。

One atom of oxygen is linked to the nitrogen atom by a double bond.

一个氧原子以双键与氮原子相连。

youdao

It's a sigma bond, - and it's going to be -- N2sp3 no. OK, it's going to be nitrogen 2 s p 3, because it's a nitrogen atom, 1s and then hydrogen 1 s.

它是sigma键，它是-,不，OK，它是，因为这是个氮原子，然后是氢。

So in terms of the first step of skeletal structure, this is actually going to be easier because we don't have a central atom, we just have carbon and nitrogen here.

对于第一步画出骨架，其实比刚才更容易,因为我们没有一个中心原子，我们这里只有碳和氮两个原子。

They were structurally similar to cytisine in many ways, sharing the location of a nitrogen atom in a particular place on a pair of bicycle-like carbon rings.

FORBES: Tobacco-Free

So Coe moved a nitrogen atom, too, and suddenly had a series of compounds to test that did exactly what Pfizer had wanted a drug to do.

FORBES: Tobacco-Free

He found a 17-year-old paper written by University of Maryland researcher Paul Mazzochi that mentioned how moving a nitrogen atom in a morphine molecule caused its morphinelike properties to disappear--and also made it poisonous, just like nicotine.
