Some nitrogen atoms have more neutrons than others.

某些氮原子比另一些氮原子拥有更多的中子。

A nitrogen atom bonded with another nitrogen atom is one of the most stable molecules on Earth.

两个氮原子结合组成的分子是世界上最稳定的分子之一。

Cyanide is a carbon atom triple bonded to a nitrogen atom.

氰离子（cyanide），是碳原子与氮原子以三键结合（C≡N¯）。

The strength of that bond means that when two nitrogen atoms snap together, they release a tremendous amount of energy.

这样的强度意味着当两个氮原子结合在一起时会释放巨大的能量。

While alkaloids as a whole are a broader group of naturally occurring organic compounds, defined by having at least one nitrogen atom.

而生物碱作为一个整体是一个更广泛的自然存在的有机化合物组，定义为至少有一个氮原子。

It has 14 nitrogen atoms and because of the way the molecule was structured, none of them are in a triple bond.

它有14个氮原子，由于其特殊的分子结构，没有一个原子处在三价键中。

And it turns out nitrogen atoms can have either seven or eight neutrons and remain stable—so nitrogen has what chemists call two stable isotopes.

氮原子可以有7到8个，某些氮原子比另一些氮原子拥有更多的中子，保持稳定的中子。因此氮原子含有化学家所说的两种稳定同位素。

As these electrically charged particles strike the atmosphere, they excite the oxygen and nitrogen atoms, causing them to light up in the beautiful colors of an aurora.

随着这些带电粒子轰击着大气层，激发了氢原子和氮原子，导致粒子发光，产生五光十色的极光。

Thalidomide, which is made up of three connected rings of carbon and nitrogen atoms, plus some oxygen and hydrogen, is what's known as a chiral molecule.

萨力多胺，由三个碳原子和氮原子的连接环以及一些氧和氢组成，也被称为手性分子。

They’re formed when the amino acids in meat are exposed to oxides of nitrogen, compounds where a nitrogen atom and an oxygen atom are bonded together.

它们是在肉中的氨基酸暴露于氮氧化物时形成的，氮氧化物是氮原子和氧原子结合在一起的化合物。

Like caffeine, theobromine is a type of alkaloid, which is a huge class of molecules that generally contain rings with at least one nitrogen atom in them, and alkaloids often have physiological effects on humans and other animals.

和咖啡因一样，可可碱属于生物碱的一种，生物碱是相当大的一类分子，一般来说它的环中会包含至少一个氮原子，生物碱通常会使人类及其他动物产生生理作用。
