As well as daylight, halogen spotlights illuminated his bench.

和日光一样，卤素聚光了他的长凳。

That mix of colors, overall, glows bright white, like a halogen bulb in a beam.

混合的颜色就会发出像卤素泡一样的白色光束。

And so let's look at the halogens which are right here.

我们来看一下这里的卤素。

Much of the interest in perovskites comes because those which combine metal atoms with chlorine, bromine or iodine (members of a group of elements called halogens) are semiconductors.

人们对钙钛矿的兴趣很大，因为那些将金属原子与氯、溴或碘（卤素元素组的成员）结合在一起就是半导体。

In addition to the extreme heat burning, melting and distorying anything it touches, lava releases particles into the air and toxic gases such as sulfur, carbon dioxide and halogen.

除了超级热的燃烧，融化熔岩向空气中释放颗粒和有毒气体，如硫，二氧化碳和卤素。

Halogens can react with metals to form halide crystals, in which the atoms become arranged in a very orderly grid called a lattice.

卤素能与金属反应生成卤化物晶体，晶体中原子以非常有序的格子排列，称为晶格。

If a halogen, such as bromine, is added in the place of hydrogen, the reaction is called halogenation.

如果用卤素（如溴）代替氢进行反应，这种反应称为卤化。

Silver halides are just some atoms of silver bound to atoms of any element known as a halogen, which includes things like bromine, chlorine, and iodine.

卤化银由银原子与卤素原子组成，卤素原子包括像溴、氯、碘等元素。

Halogens, Noble gases, lanthanides or rare earth elements.

卤素、惰性气体、镧系元素或稀土元素。

It might be a long hydrocarbon chain or a halogen or an oxygen.

它可能是一个长的碳氢化合物链，或者是一个卤素，或者是一个氧。

Wearing a thin gown, I seem to float through a hallway lit by halogens.

身着单薄的长袍，我仿佛漂浮在由卤素的走廊中。

Other molecules can break that double bond as well. If a halogen, such as bromine, is added in the place of hydrogen, the reaction is called halogenation, a water molecule, hydration, oxygen, gas, oxygenation. You get the idea.

其他分子也能断裂该双键。如果用卤素（如溴）取代氢，则该反应称为卤化；若加入水分子，则称为水合；若加入氧气，则称为氧化。以此类推。

He's pushed hard in the back and he stumbles out onto the painted grass under bright halogen lights.

他被人在背后猛推了一把，踉跄地走到了明的卤素下那片绘制出来的草地上。

Lighting, whether it’s the sun or halogen, incandescent, or fluorescent lights, change

光线， 无论是太阳光是卤素、白炽或荧光， 都会改变颜色。

The granite pyramid looked almost austere in the clean halogen light. Katherine ran her fingers over the engraved Masonic cipher, and Langdon sensed deep emotion churning within her.

花岗岩金字塔在干净的卤素下看起来几乎简朴。凯瑟琳用手指扫过刻有共济会密码的图案, 兰登感觉到她内心深处涌动的情感。

How many electrons would halogens have to get in order for them to move to a noble gas?

卤素需要获得多少个电子才能转变为稀有气体？

Halogens are going to have the same valence electrons, but as we go to fluorine, chlorine, bromine and iodine, we're actually going to go from gases, fluorine, chlorine, to liquid bromine and then solid iodine.

卤素将具有相同的价电子, 但是当我们进入氟、氯、溴和碘时, 我们实际上将从气体、氟、氯进入液体溴, 然后进入固体碘。

Also it's going to explain why as we go down in the periodic table, let's look at the halogens right here.

它将解释为什么随着我们在元素周期表中往下看, 让我们看看这里的卤素。
