图像的空间分布就代表了原子周围的电子密度。

The spatial distribution of that image represents the electron density around the atom.

还记得在这个离子中，在原子核周围，抵消它吸引力的电子更少。

Remember in the ion, we're going to have less electrons around to counteract the pull from the nucleus.

So in order to fill them, he would have to have eight electrons or an octet around the cubes.

因此为了填满它们，他必须放上八个电子或者说一个“八隅体“,在立方体周围。
