Model | In science, a diagram, a mental picture, a mathematical statement, or an object that helps explain ideas about the natural world |
Describe the structure of an atom | Atoms are made of even smaller particles called protons, neutrons and electrons. |
Describe the elements in terms of their atoms | An element can be identified by the number of protons in the nucleus of its atoms |
Explain how models are useful for understanding atoms | Because atoms are so small, scientist create models to describe them |
