Perhaps future astronomers will note whether its dark matter shroud once again saves the cloud.

也许，未来科学家就可以确定是不是保护了暗物质云免受撞击带来伤害了。

It's a bright shell of radiation that we are encased in.

它是我们所处明亮辐射。

And then you start filling the second energy shell.

然后开始填充第二能。

And sometimes we have to go to the shell model however to explain new phenomena.

然而, 有时我们必须使用模型来解释新现象。

The resulting positive and negative ions are held together by electrostatic forces a process called ionic bonding The repetitive order in which the shells are filled in each row means that elements in each column of the table.

形成正离子和负离子通静电作用力结合在起，这个程称为离子键合。每行中电子依次填充重复顺序意味着表格中每元素。

For example chemists who use " wrong" electron shell models  to work out chemical bonds or scientists using simplified models as the basis of discussions with  colleagues across different scientific fields.

例如，化学家使用“错误”电子模型来计算化学键，或者科学家们在不同科学领域与同事讨论时使用简化模型。

Chemical reactions happen when an atom's outermost electrons do stuff, and the protons and neutrons and even the inner electron shells are usually completely unaffected.

当原子最外电子做事时就会发生化学反应，而质子和中子甚至内电子通常完全不受影响。

Some thought it was hollow, maybe a set of concentric shells with life on each  ring.

有人认为地球是空心，或许是由系同心构成，每都有生命存在。

And then it would have 8 electrons in the next shell.

然后在下个中会有 8 个电子。

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.

它们由重叠电子云或电子形成，围绕着结合原子核流动。 如果你深入理解它们样子， 它们就像团团不规则概率电子位置分布。

It is the shells that define the table's rows In the first row, which consists of hydrogen one electron and helium two.

是电子定义了表格行。在第行中，包含氢个电子和氦两个电子。

And then, of course, it filled up at the first shell before it could fill up these other shells.

当然，它在填满其他之前，先填满了第。

It'll maybe go into this shell out here.

它可能会进入这个。

We're in the first energy shell.

我们在第能。

And so the first electron will go right here in the 1s energy shell.

那么第个电子将会进入1s能。

And what does that first orbital subshell, that s-shell, look like?

那么第个亚轨道，也就是s，是什么样子？

It'll be like this shell that's around the center.

它将像围绕中心个那样。

And you can see it a little bit better in, actually, the higher energy orbits, the higher energy shells, where the seventh s energy shell is this red area.

实际上， 在更高能量轨道或更高能量中， 你可以更清楚地看到这点，第七个s能就是这片红色区域。

And now you see that helium, you get 1s and then you get 2s, so helium's configuration is -- Sorry, you get 1s1, then 1s2.

而现在你看氦元素，你先得到1s，然后是1s1，接着是1s2。我们在第能。

That's where the eight rule breaks down in the first shell.

那是第中八隅律失效地方。
