Polyhedron ball-and-stick model

Abstract

A polyhedron ball-and-stick model comprises a plurality of geometric model polyhedrons representing atoms and cylindrical connecting rods with different lengths representing connecting keys and being connected with the atoms in a space-filling model, wherein the geometric model polyhedrons comprise regular polyhedrons formed by congruent regular polygons, semi-regular polyhedrons formed by two or more than two regular polygons and polyhedrons formed by other polygons, the center position of each surface of each polyhedron is provided with a circular hole groove having the same diameter and the same depth, and the diameter of each circular hole groove is identical with the diameter of the end portion of each cylindrical connecting rod to allow the end portions of the connecting rods can be inserted into the circular hole grooves on each surface of the polyhedrons. The problem is solved that the spherical circular hole groove is difficult to locate in a traditional ball-and-stick model, and the polyhedron ball-and-stick model can be more rapidly and accurately assemble a desired space-filling model.

Description

Technical field [0001] The invention relates to a teaching article, especially a ball and stick model. Background technique [0002] The ball and stick model is a space filling model used to represent the three-dimensional spatial distribution of chemical molecules. The earliest ball-and-bat molecular model was made by the German chemist August Wilhelm von Hofmann for the purpose of lectures. In the traditional ball-and-stick model, due to the complex bond angles and bond lengths between atoms in the space structure model, the connecting rods representing the connecting bonds and the spherical bodies representing the atoms cannot be assembled arbitrarily to get the user's imagination. The space structure to be expressed and the existence of different bond angles also increase the difficulty of determining the position of the groove on the surface of the spherical body. [0003] Therefore, designing a ball and stick model that can simultaneously solve the problems of complex bond ...
