MM OLECULE MODELS IN THIS CHAPTER YOU LEARNED ABOUT olecule Models


In this chapter, you learned about atoms and the bonds that form between them. To illustrate bonding, chemists use ball –and-stick modeling kits. These kits usually contain balls that represent the atoms, and sticks that represent the chemical bonds between the atoms. The balls are usually color-coded with different colors representing different elements. Different stick types are usually included so that different types of chemical bonds (single, double, or triple) can be modeled.


In this project, you will create your own modeling kit. Your kit will contain several different atoms. They will also contain chemical bonds that you will use to join the atoms together. You will use these kits to create compounds that contain ionic and covalent bonds.
