Warm Up Survey Marshmallow Molecules We'll use the same color code that chemists do for their models: Black = carbon White = hydrogen Red = oxygen Blue = nitrogen (Okay, these are purple in the photos since I didn't have blue.) Green = chlorine Yellow = sulfur Orange = phosphorus Here are some easy ones you can try: And here are a few that are a little trickier: In these models, each gumdrop represents one atom. Almost all atoms have tiny particles called electrons that they can use to connect to other atoms. In these models, the toothpicks represent bonds that hold the atoms together. The bonds are formed by the atoms sharing those electrons with each other. Word Web
