The rest, a sphere of influence about as large as the Eiffel tower from your perspective, is filled with an electron cloud.

剩下的会是以一个在你看来和艾菲尔铁塔同高的影响球体存在，里头充满了电子云。

They form from overlapping electron clouds or shells, flowing around the nuclei of bonded atoms.

它们由重叠的电子云或壳形成， 围绕键合原子的原子核流动。

You know those electron clouds you'll sometimes see in models of atoms?

你有时知道你身上的那些电子云 在原子模型中看到了吗？

The area where you might find it if you tried to measure it is called the electron cloud.

如果你试图测量它，你可能会发现它的区域称为电子云。

But if you’re studying chemical bonds, you might need the electron cloud model to know where the electrons are.

但如果你正在研究化学键，你可能需要电子云模型来了解电子的位置。

So, the electron cloud model is the most up-to-date model of an atom, and it’s used by scientists around the world.

因此，电子云模型是最新的原子模型，全世界的科学家都在使用它。

The " shell" of an atom isn't some hard shiny casing, as illustrations sometimes encourage us to suppose, but simply the outermost of these fuzzy electron clouds.

原子的壳并不是某种坚硬而光滑的外皮，就像许多插图有时候怂恿我们去想像的那样，而只是这种绒毛状的电子云的最外层。

They form from overlapping electron clouds or shells, flowing around the nuclei of bonded atoms. If you really get down there and understand what they look like, they're like lumpy, clumpy globs of probable electron locations.

它们由重叠的电子云或壳形成，围绕键合原子的原子核流动。 如果你真的深入了解它们的样子， 它们就像可能是电子位置的块状团块。
