2. Bohr-Rutherford models are two dimensional models of compounds. A Bohr-Rutherford model shows the electron arrangement within each atom of a compound. Three-dimensional models illustrate valuable information about compounds, including the bonding arrangement of the atoms or ions.

3. Two types of three-dimensional models are ball-and-stick models and space filling models. Ball and Stick models show the overall shape of a molecule, and space filling models emphasize the relative sizes of the atoms or ions.

4. Examples of Ball and Stick models in our bodies and everyday life: Animation
