And all those free electrons are great at conducting electricity.

而那些自由电子有很好导电性。

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

自由电子和金属产生振荡与可见光波。

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

这是一个大事件！自由电子非常擅吸收光子，吸收光。

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

为了释放电子，必须使电子高速旋转而足以摆脱原子核束缚。

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， 中有自由电子在中移动。

These moving electrons are called free electrons.

电子可以自由移动，称为 这些移动电子：电子。

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电荷物体时， 我们是它缺少自由电子。

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 正总电荷，我们是。

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

这些额外自由电子会尽可能多地离开 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.

当这些自由电子从电极一端涌向另一端，它们会与更多氖原子碰撞，并使自身也离子化。

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电子激光仪。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.

色散量告诉您无线电波必须通过多少个自由电子才能到达检测器。

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

电池内部发生化学反应称为电化学，因为它涉及产生或消耗自由电子反应。

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，想象一个带有总电荷携带球 负，味着它有额外自由电子。

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.

等离子体就像种气体，除了它原子上一些电子被扯下来了，所以它是由正离子组成，再加上很多自由电子在旁边乱转。

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.

在大爆炸后最初几秒钟，宇宙是自由电子和原子核海洋，温度高得令人难以置信， 密度大到连光子都无法逃脱那台不透明宇宙弹球机。
