Application: The electronic cloud model is applied to the teaching of electronic cloud, hybrid orbit and other contents in high school chemistry class, which can enhance the intuitiveness of the teaching of this part of the content and make it easier. Made of polyethylene plastic, metal material, durable and lightweight. The S electron cloud is completely symmetrically distributed around the nucleus. The shape of the interface of the electrons on the S layer in the area where the nucleus often appears is a sphere with the nucleus as the center. The degree of extension of the S electron cloud in all aspects of the outer space Are the same. The shapes of electron clouds on the S layer in different electron layers are all spherical, and the only difference is that the area with the largest electron cloud density is different from the nucleus. The P electron cloud D is shaped like a handleless dumbbell. The P electron cloud has three different extension directions PX, PY and PZ in space. its energy is equal. The density of the electron cloud increases towards the ends of the extension, and the density of the electron cloud at the core is 0.
