Embodiment 1

[0018] Example 1 (see image 3 ): A magnetic ball 2 is inserted on the rounded square iron wire 3, and a hydrogen atom symbol with an orange background color is pasted on the circular magnetic iron sheet 1. Two similar devices are close to each other, indicating that two hydrogen atoms share A pair of electrons, which in turn demonstrates the nonpolar covalent bond contained in the hydrogen molecule.

Embodiment 2

[0019] Example 2 (see Figure 4 ): five magnetic balls 2 are inserted on the rounded square iron wire 3, and a nitrogen atom symbol whose background color is dark blue is pasted on the magnetic iron sheet 1; two similar devices are close to each other, and each side has three A magnetic sphere 2, which shows that two nitrogen atoms share three pairs of electrons, and then shows the non-polar covalent bonds contained in nitrogen molecules.

Embodiment 3

[0020] Embodiment 3 (see Figure 6 ): insert a magnetic ball 2 on the rounded square iron wire 3, paste the hydrogen atom symbol with orange background color on the magnetic iron sheet 1; insert seven magnetic balls on another rounded square iron wire 3 2. A chlorine atom symbol with a green background color is pasted on the magnetic iron sheet 1. The two devices are close to each other, and there are two magnetic balls 2 on the side close to each other, which means that the hydrogen atom and the chlorine atom share a pair of electrons. , which in turn demonstrates the polar covalent bonds contained in the HCl molecule.

[0021] In summary, with this device, the covalent bonds between small molecules such as simple molecules, hydrides, and oxides that are common in middle school chemistry can be displayed and inspired, allowing students to deepen their understanding of abstract concepts during hands-on operations, increasing their Interesting, deepens the impression, and make...

Abstract

The invention relates to an electronic demonstration model of covalent bond forming molecules, which is composed of a circular magnetic iron sheet, a magnetic ball and a rounded square iron wire, thecircular magnetic iron sheet and the rounded square iron wire are welded through a thin iron wire, and the magnetic ball representing electrons is inserted into the rounded square iron wire. A grooveis formed in the magnetic ball from the diameter to the spherical surface of one side. The surface of the circular magnetic iron sheet is covered with element symbols representing atoms, and the thickness of the circular magnetic iron sheet is larger than or equal to the diameter of the magnetic ball. The electronic demonstration model has the advantages that the structure is simple, abstract chemical theories can be visualized and embodied, and the phenomenon is obvious; students can understand and experience in manual operation, diatomic molecules and polyatomic molecules can be displayed, polar bonds, non-polar bonds and peripheral electron arrangement knowledge are embodied, and the learning interest of the students is increased.

Description

technical field [0001] The invention relates to a chemistry teaching demonstration model, in particular to an electronic demonstration model of covalent bond forming molecules. Background technique [0002] We know that there are interactions when atoms combine to form molecules. This strong interaction between adjacent atoms is the chemical bond. Chemical bonds include ionic bonds, covalent bonds and metal bonds. Among them, the writing of electronic and structural formulas in covalent bonds is the focus and difficulty. These knowledge points and concepts often make beginners confused. How to let students better master these A lot of thought has been put into the knowledge points, teachers, teaching materials and supplementary materials, but the effect is not satisfactory. How to better root these knowledge points in the minds of students, how to better memorize, display and understand, and whether they can be displayed with physical models, there is no attempt in this re...
