So each molecule has a dipole moment.

所以每个分子都有一个偶极矩。

Water and its useful little dipole moment can dissolve more compounds than any other chemical on Earth.

水及其有用的小偶极矩可以溶解比地球上任何其他化学物质更多的化合物。

In order for a molecule to be polar, there has to be a dipole moment, a separation of the charge around the molecule into a more positive area and a more negative area.

为了使分子具有极性，必须存在偶极矩，将分子周围的电荷分离为更正的区域和更负的区域。

Ionic solids are basically just polarity taken to the extreme, so far that instead of having a partial positive and partial negative dipole moment, the electrons have completely transferred, creating two charged ions.

离子固体基本上只是极端的极性，到目前为止， 电子已经完全转移， 而不是具有部分正偶极矩和部分负偶极矩， 从而产生两个带电离子。

You also learned how to notate a dipole moment or charge separation of a molecule, the actual physical mechanism behind " like dissolves like" , and why water is just so dang good at fostering life on this planet.

您还学习了如何记下分子的偶极矩或电荷分离、“同类相溶”背后的实际物理机制，以及为什么水在培育这个星球上的生命方面如此出色。
