Metals, Nonmetals, and Metalloids
Storyboard Text
- METALS:1. Usually solid at room temperature (except for Mercury)2. Found to the left of the "staircase line"3. Make up the majority of elements that are found in the periodic table4. Luster (They are shiny)5. Ductile (able to be bended into a wire)6. Malleable (able to be hammered/rolled into sheets without breaking)7. Good conductors of heat and electricity; Poor insulators8. High melting point9. High density10. Bright light
- Gold
- Iron
- NONMETALS:1. Vary in states of matter at room temperature2. Found to the right of the "staircase line"3. Make up a minority of elements found in the periodic table4. No luster (They all dull)5. Not ductile5. Not malleable7. Poor conductors of heat and electricity; Good insulators8. Low melting point9. Low density10. No light
- Sulfur
- Oxygen
- METALLOIDS:1. Solid at room temperature2. Concentrated around the "staircase line"3. Only 7 elements (Boron, Silicon, Germanium, Arsenic, Antimony, Tellurium, and Polonium) are metalloids4. Can be shiny OR dull5. Can be ductile OR brittle6. Can be malleable OR brittle7. Semiconductors; conduct heat/electricity better than nonmetals, but worse than metals8. Melting point varies9. Density varies10. Dim light
- Silicon
- Boron
