TIANQIHAO Graphite Crystal Structure Model Large Ball And Stick Model Graphite Crystal Structure Model For Chemistry Teaching Demonstration Tools Educational Aid Chemistry Equipmen
TIANQIHAO
This model is used for the demonstration of chemistry-related crystal structure content, and give students the most profound influence in chemistry class. Product structure: 39 carbon 5-hole black balls, 20 long keys, and 45 short keys. Graphite crystals have a layered hexagonal crystal structure. The carbon atoms in each layer form many hexagonal atomic rings, and the atoms are connected by covalent bonds. The distance between carbon atoms is equal to 1.1415A, and the distance between layers is 3.35A. TInk plastic balls are used to represent carbon atoms, which are connected by long and equal bonds to form a graphite crystal structure as shown in the figure.
