Molecular structure and chemical bond classification assembling model for chemical teaching

Abstract

The present invention discloses a molecular structure and chemical bond classification assembling model for chemical teaching. The model comprises an atom model and a chemical bond model, the atom model is made of elastic rubber and is configured to differentiate the atomic species according to different colors and radiuses, and a plurality of jacks are uniformly arranged at the surface of the atom model; the chemical bond model comprises a [Sigma]-bond model and a [Pi]-bond model, the [Sigma]-bond model is made of rigid plastic materials, the [Pi]-bond model is made of elastic rubber materials, the chemical bond model is a rod-shaped configuration and two ends of the chemical bond model are provided with plugs, the middle portion of the chemical bond model are provided with breaking points, the breaking points are connected through flexible glue sleeve, and the breaking points are configured to demonstrate the broken bond re-connection process of the chemical bonds in the chemical reaction. The molecular structure and chemical bond classification assembling model for chemical teaching can be used for demonstration of a molecular structure and chemical reaction process in the chemical teaching to allow teaching to be more visual and clear, facilitate deep understanding of students to the chemical reaction principle and process and improve the teaching effect.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a molecular structure and chemical bond classification assembly model for chemistry teaching. Background technique [0002] Chemistry is a compulsory subject for science middle school students, and it is also the basic knowledge that people must possess to understand the world, understand science, and improve their scientific literacy. Chemistry is a science that studies the structure and composition of matter and its changing laws and principles. Microscopic changes are the root of macroscopic changes. Limited by the conditions of middle school classrooms and the consideration of student safety, many schools do not have the ability to open large-scale chemistry. The ability to experiment, and even if the experimental conditions permit, students still cannot fully understand the microscopic state of chemical substances and chemical reactions, so the auxiliary demonstration of teachin...
