We use a catalyst and we then start to knock off these fluorine atoms.

用催化剂，然后开始分解这些氟原子。

Fluorinating agents rip other molecules apart to replace their hydrogen atoms with fluorine.

氟化剂会打破分子结构，然后用氟取代原来氢原子。

The fluorine atoms surround the carbon like armor, spiraling around the chain, and the bond between carbon and fluorine is incredibly tight.

围绕着碳原子氟原子就像是盔甲一样，在链边旋绕，碳原子和氟原子之间纽带很紧。

A U. S. military base in Japan has acknowledged three incidents of chemical leakage containing organic fluorine compounds that raise health concerns.

驻日美军军事基地承认三起含有有机氟化合物化物质泄漏事件，这些事件引起了健康问题。

So hydrogen bond is going to occur when we have hydrogen bonded to either a nitrogen, oxygen or a fluorine.

因此, 当氢与氮、氧或氟结合时, 就会发生氢键。

The ash is coated with mineral salts, and they're mainly sulfur and chlorine and sometimes fluorine.

火山灰上覆盖着矿物盐，主要是硫和氯，有时还有氟。

Like a couple that ignores everyone except each other, carbon and fluorine interact so strongly, that the normal, intermolecular forces that help substances stick to each other don't stand a chance.

就像一对无视他人情侣，碳原子和氟原子强烈地相互作用，造成普通帮助物质黏在一起作用于分子间力根本不起作用。

It's much more dangerous to handle than even fluorine gas, which as anyone with a degree in chemistry could tell you is not a sentence that you get to say very often.

氟火处理起来甚至比氟气还要危险得多，任何有化人都会如此告诉你，当然这句话他不会有机会经常讲。

Oxygen, nitrogen, fluorine, chlorine, and bromine are basically the One Direction of the periodic table.

氧、氮、氟、氯和溴基本上是元素周期表上单向乐队。

We go to fluorine, we go to neon.

去氟, 去新星。

So as soon as another molecule wanders too close, the fluorines lose all their hydrogens and bond with the new molecule instead — pretty much no matter what it is.

因此一旦另一种分子靠足够近，氟就会失去所有氢，然后去和新分子结合——不论新分子是什么。

A PTFE chain has a backbone of carbon atoms, each of which is attached to two fluorines.

一个PTFE链有碳原子主链，每一个碳原子还连接两个氟原子。

The result is what chemists called a 'violently exothermic reaction', in this case known as a fluorine fire.

产生结果被化家称为“剧烈放热反应”，也就是氟火。

Especially exciting is that fluorine really likes to bond with calcium.

特别值得一提是氟很喜欢与钙结合。

Hydrogen bonds are going to form when we have hydrogen bonded to either oxygen, nitrogen or fluorine.

当氢与氧、氮或氟结合时, 就会形成氢键。

Once it's lost its hydrogen atoms, the remaining atoms of fluorine and another element, antimony tear through everything else around them, ripping electrons off nearby molecules and leaving just organic goo in their wake.

一旦它失去了它氢原子，剩下氟原子和锑原子就会穿透周围任何物质，抢夺附近分子电子，身后只留下一堆黏糊糊有机物。

And remember from Substance N how crazy fluorine is.

回想一下“物质N” ，就知道氟有多疯狂。

It is one that chemists will handle commonly, but extremely  carefully, as it is capable of dissolving glass, metals, and penetrating tissue and bones due to  the highly reactive fluorine it contains.

这种物质化家会经常接触，但必须极其小心，因为它含有高度反应性氟， 能够溶解玻璃、金属， 并能穿透组织和骨骼。

Then, there's hydrogen bonding, a special type of dipole-dipole force, one that occurs on polar molecules that contain hydrogen and a strongly electronegative element such as nitrogen, oxygen, or fluorine.

然后是氢键，一种特殊类型偶极-偶极力，发生在含有氢和强电负性元素（如氮、氧或氟）极性分子上。

There was also widespread mercury poisoning and toxic fluorine and chlorine gas, which would have been familiar to suffocating soldiers in the First World War trenches.

此外， 还出现了大范围汞中毒和有毒氟气及氯气，这些有毒气体对于一战战壕中窒息士兵来说并不陌生。
