And this notion, where you're actually sharing electrons, where these electrons are going to go and both electron probability distribution clouds of both atoms. This is called a covalent bond.

这个概念，你实际上是在共享电子，这些电子将去往哪里， 以及两个原子的电子概率分布云。 这称为共价键。

It's when that atom is part of a covalent bond, when it is sharing electrons with another atom, how likely is it or how badly does it want to hog the electrons in that covalent bond?

当那个原子是共价键的一部分时，当它与另一个原子共享电子时， 它有多大可能或者它想要在那个共价键中占据电子的可能性有多大？
