And all those free electrons are great at conducting electricity.

而那些自由有很好的导性。

The free electrons in metals are especially good at this vibrating-to-match-visible-light thing.

自由和金属产生的振荡与可见光波长匹配。

This was an important event! Free electrons are really really good at absorbing photons, absorbing light.

这是一个大事件！自由非常擅长吸收光，吸收光。

To free electrons, something has to make them whirl fast enough to break away from their nuclei.

为了释放，必须使高速旋转而足以摆脱的束缚。

So we’ve got insulators and conductors with free electrons moving around in them.

所以我们有绝缘体和导体， 中有自由在中移动。

These moving electrons are called free electrons.

可以自由移动，称为 这些移动的：。

And when we talk about an object having an overall positive charge, we mean it’s missing free electrons.

当我们谈论一个整体带正荷的物体时， 我们的意思是它缺少自由。

And when we talk about an object having an overall positive charge, we mean it's missing free electrons.

当我们谈论一个元素时 正总荷，我们的意思是。

These extra free electrons want to move as far away from one another as possible.

这些额外的自由会尽可能多地离开 彼此可能。

As these free electrons rush from one electrode to the other, they collide with more neon atoms, causing them to ionize as well.

当这些自由从极的一端涌向另一端，它们会与更多的氖碰撞，并使自身也离化。

Sheldon, I told you, I only have access to the free electron laser at night. I can't drive you for the next few weeks.

谢尔顿我跟你说过了，我只有晚上才能用自由激光仪。接下来几个礼拜我都不能开车送你了。

And the amount of dispersion tells you how many free electrons that radio wave had to pass through to reach the detector.

色散量告诉您无线波必须通过多少个自由才能到达检测器。

The kind of chemistry that happens inside of a battery is called electrochemistry because it involves reactions that produce or consume free electrons.

池内部发生的化学反应称为化学，因为它涉及产生或消耗自由的反应。

The answer is an imbalance of electrical charge, when some part of an object has a different number of free electrons than another part.

基本上？

To figure this out, let's imagine we have a conductive sphere with a net negative charge meaning it has too many free electrons.

为了找出答案，想象一个带有总荷的携带球 负的，意味着它有额外的自由。

Plasma is kind of like a gas, except that its atoms have some of their electrons stripped off, so it's made up of positively-charged ions and a bunch of free electrons zooming around.

等离体就像种气体，除了它上的一些被扯下来了，所以它是由正离组成的，再加上很多自由在旁边乱转。

In the first few seconds after the Big Bang, the universe was a sea of free electrons and atomic nuclei, so unbelievably hot and dense that not even photons could escape that opaque cosmic pinball machine.

在大爆炸后的最初几秒钟，宇宙是自由和的海洋，温度高得令人难以置信， 密度大到连光都无法逃脱那台不透明的宇宙弹球机。
