- Most substances have a density greater than water and will sink when placed in it
- An experiment can be conducted to compare the densities of different materials and observe their behavior in water
- Elements with a density greater than water will sink when submerged
- A graph can visually represent the densities of different materials compared to water
- Nonmetals have a greater density than water and will sink when placed in it
- The most reactive nonmetal is fluorine
- Metalloids are classified as semiconductors and share properties of both metals and nonmetals
- Most reactive metals are found in the lower left portion of the periodic table
- Group 1, the Alkali Metals, are extremely reactive and can burst into flame when in contact with water
- The Noble Gases are the least reactive due to their complete valence shell
