Practice Decide if these are elements, compounds, or molecules 1. N20 2. Ba (Barium) 3. O3 Compound or molecule Element Element or molecule

Build A Molecule Example: Hydrogen H H Draw your molecules in your Application /Connection section , label the atoms used, and name the chemical formula Example: Hydrogen Molecule Chemical Formula 2-Hydrogen H Hydrogen H2 H Hydrogen

Draw and label these molecules Build A Molecule With your shoulder partner, build the molecules below: Remember to label and Color. Largest Element always goes in the middle. Draw and label these molecules Water Carbon Dioxide Sulfur Molecule Glucose Nitrogen Molecule Key Hydrogen=white Oxygen=Green Sulfur=Yellow Carbon=Orange Nitrogen=Pink
