189PCS Molecular Structure Model Colorful PP Educational Organic Chemistry Model Kit for Class

About this item

• Feature: 1. 3D MODEL: This model shows chemical structures, molecular bonds and bond angles in all directions, demonstrating basic molecular geometry, chemical molecular structures and stereochemistry through 3D modelling studies. 2. EUDCATIONAL MODEL: This molecular structure model will stimulate children s interest in learning, exercise their hands on skills and expand their spatial imagination. 3. TEACHING AID: The model can be used in chemistry textbooks to represent the structure of various molecules of inorganic and organic substances, allowing teachers to explain them more visually. 4. EASY TO LEARN: The common standard used for each atomic colour makes it easier for you to use and learn, and can be used to construct a wide range of common and slightly more complex C, H, O and N. 5. SIMPLE INSTALLATION: The atoms and chemical bonds are tightly and firmly bonded together and can be easily disassembled with a disconnecting tool. Specification: Item Type: Molecular Structure Model Material: PP Use: This set of models contains atoms of carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur, chlorine, bromine and monovalent metals, and allows the construction of ball and stick and scale models of common substances found in secondary school chemistry textbooks such as alkanes, alkenes, alkynes, aromatic hydrocarbons such as benzene, halogenated hydrocarbons, alcohols, ethers, phenols, aldehydes, ketones, carboxylic acids and esters, as well as common inorganic substances..
