• a complex mathematical equation describing electron behavior.

• a miniature solar system with planets orbiting a central nucleus

• a positively charged sphere with negatively charges scattered throughout

Why do scientists use models?

• They are exact representations of reality.

• They only exist in computer simulations.

• They are always simple and easy to understand.

• They can be used to test ideas and make predictions.

• An image (picture, concept map, flowchart, etc.) that considers all laws of science.

• A round Styrofoam colored with parts representing electrons and other subatomic particles.

• A computerized interactive game where you can put subatomic particles and guess the correct image for atom.
