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

我们使用催化剂，然后开始分解这些原子。

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

化剂会打破分子结构，然后用取代原来氢原子。

And remember from Substance N how crazy fluorine is.

回想一下“物质N” ，我们就知道有多疯狂。

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

山灰上覆盖着矿物盐，主要硫和氯，有时还有。

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

产生结果被化学家称为“剧热反”，也就。

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

特别值得一提很喜欢与钙结合。

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.

围绕着碳原子原子就像盔甲一样，在链边旋绕，碳原子和原子之间纽带很紧。

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

如果电子 13 岁女孩，就 Niall Horan。

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

聚合它而不氢， 聚合物完全与结合。

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

好吧，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，在有机物中测量吸收率用于测年早期石化吗？

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

由于极端电负性， 因此摩擦较小。

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

元素一开始与大量氢元素结合，但他们很快会用其他物质代替氢。

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

氧、氮、、氯、溴基本上元素周期表一个方向。

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

现在，如果你用改变基础乙烯上所有四个氢， 它就会变成四乙烯。

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

因此，对于氢键，您该记住三种负电性元素、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位置猜到喜欢电子。 它具有极强负电性。

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化合物化学物质泄漏事件，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， 只有一个电子 1s1。 对于，它 1s2 2s2 2p5。
