The first one will be above and below the bond axis is where we'll see the electron density, and the second will be perpendicular to that, so it will be a density in front of and behind the bond axis.

第一个是在键轴之上和之下,我们可以看到电子密度，另外一个垂直于它，所以在键轴之前和之后有电子密度。

And as a result of that, the achieving of octet stability via electron transfer tumbled to the idea of an ionic bond where one atom donates an electron completely to the other atom, sort of like servanthood.

有了他们，也就是形成八隅体的稳定结构,通过电子的扰动形成理想的离子键,这儿一个原子完全将一个电子,给另一个原子，有点像奴仆关系。
