Features

• A set that can learn molecular shapes, electron orbitals, and assemble eight different structures.
• You can compare molecules with different bond angles and coordination numbers, learn the valence shell electron-pair repulsion rule (electron pair repulsion theory and VSEPR theory), and express protonation.
• Assembly Model: HCl Hydrogen Chloride, BeCl2 Beryllium Chloride, H2O Water, BH3 Monoborane, NH3 Ammonia, CH4 Methane, PCl 55 Phosphorus Chloride, SF 66 Sulfur Fluoride
• Features of molymod (R) molymod Molecular Structure Model Series
• Strong, hard to break, and refillable.
• Simple assembly and disassembly
• There are 1~6 bonding holes made by atoms, allowing the assembly of various molecular structure models.
• The paddle represents the orbit of an electron. (* Only applicable set.)
• It is possible to create open and filled models with single and multiple bonds.
• * Molymod (R) is a registered trademark of Spiring Enterprises Limited, West Sussex, England. *The scale is roughly 3.5 cm=1Å.
