Scientists use models to help them represent things in nature that they cannot observe directly. They can also use models to make predictions. For example, scientists use Bohr models of atoms to predict chemical reactions between atoms. You can use models in the same way, but you must first understand what each model component represents. Draw the electron dot diagram for the atom shown above. Explain what the letter and the dots in the diagram mean. Name another element that would have the same number and arrangements of valence electrons.
