electron cloud properties
The space around the nucleus is a negative atmosphere formed by the movement of electrons. Describe the probability of electrons in atoms or molecules appearing in various areas around the nucleus. It can be expressed in the image by the electron cloud density (the degree of the thickness of the cationic atmosphere), and the different shades represent the probability of the size, and the result is like a cloud formed by electrons around the nucleus. The spatial distribution of the electron cloud can also be represented by an iso-density surface.
