We also discussing binding energy and mass-energy equivalence, as well as the strong and weak nuclear forces.

我们还讨论了和质等效，以及强和弱。

But while the total binding energy still increases for nuclei larger than iron, the binding energy per nucleon, in fact, decreases.

但是，虽然对于比铁大的原子，总仍然增加，但实际上每个子的却降低了。

But elements with lower binding energies can react much more readily.

但是具有较低的素可以更容易地反应。

This is a graph of the binding energies of various elements compared to their mass numbers.

这是各种素的与其质量数相比的图表。

Well, that difference in mass is equal to an amount of energy, specifically the total binding energy of the nucleus.

好吧，质量差等于量，特别是原子的总。

This is known as binding energy and it's one of the fundamental principles of nuclear chemistry.

这被称为， 它是化学的基本原理之一。

That binding energy is how much energy you would have to add to the helium atom in order to break it apart its nucleus.

该是您必须向氦原子添加多少量才将其分解成原子。

To find out how much binding energy that missing mass amounts to, you can use it as the 'm' in Einstein's formula.

要找出丢失的质量相当于多少， 您可以将其用作爱因斯坦公式中的“m” 。

That energy is what we mean when we talk about nuclear energy, the binding energy that's released when a nucleon is removed from its nucleus.

当我们谈论时，这种量就是我们所说的量，即当子从其原子中移除时释放的。

And since binding energy accounts for the missing mass, you can calculate it using – you guessed it! – e equals m c squared.

由于解释了缺失的质量，您可以使用 - 您猜对了！ – e 等于 m c 的平方。

If you paid attention, you learned how Einstein's famous formula helps us calculate the binding energy of a nucleus from its mass defect.

如果您留心观察，就会了解到爱因斯坦著名的公式如何帮助我们根据质量亏损计算原子的。

The amount of energy required to break up a nucleus into its component particles gets larger as the atomic number increases, with iron having one of the highest binding energies per nucleon.

随着原子序数的增加，将原子分解成其组成粒子所需的量会变大，铁是每个子最高的物质之一。
