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

我们使用催化剂，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，然后用氟取代原来的氢原子。

And remember from Substance N how crazy fluorine is.

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，是硫和氯，有时还有氟。

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

产生的结果被化学家称为“剧烈的放热反”，也就是氟火。

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

特别值得提的是氟很喜欢与钙结合。

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

个PTFE链有碳原子的链，每个碳原子还连接两个氟原子。

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

围绕着碳原子的氟原子就像是盔甲样，在链边旋绕，碳原子和氟原子之间的纽带很紧。

If electrons were 13-year-old girls, fluorine would be Niall Horan.

如果电子是 13 岁的女孩，氟就是 Niall Horan。

Polymerize that and instead of hydrogens that polymer is bound entirely to fluorines.

聚合它而不是氢， 聚合物完全与氟结合。

Ok so fluorine is going into the apparatus, it’s going into this tube.

好吧，氟进入了设备， 它进入了这个管子。

She's asking is the absorption of fluorine that is measured in organics for fluorine dating early fossilization?

她问的是，在有机物中测量的氟吸收率是用于氟测年早期石化的吗？

The fluorines end up bonded to lots of hydrogen, but they'll drop the hydrogen in favor of just about anything else.

氟元素开始与大量的氢元素结合，但是他们很快会用其他的物质代替氢。

Which so friction-less because of fluorine's extreme electronegativity.

由于氟的极端电负性， 因此摩擦较小。

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

氧、氮、氟、氯、溴基本上是元素周期表的个方向。

Now if you change all four of the hydrogens on the base ethylene with fluorine it becomes tetrafluoroethylene.

现在，如果你用氟改变基础乙烯上的所有四个氢， 它就会变成四氟乙烯。

And so the three electronegative elements that you should remember for hydrogen bonding are fluorine, oxygen, and nitrogen.

因此，对于氢键，您该记住的三种负电性元素是氟、氧和氮。

Fluorine as we could guess from its spot on the periodic table, love electrons. It is extremely electronegative.

我们可以从它在元素周期表上的位置猜到氟喜欢电子。 它具有极强的负电性。

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的化学物质泄漏事件，这些事件引起了健康问题。

So for hydrogen, with just one electron it's 1s1. For fluorine it's 1s2 2s2 2p5.

所以对于氢来说， 只有个电子是 1s1。 对于氟，它是 1s2 2s2 2p5。
