A. Metallic Character ¨ Metals ¨ Nonmetals ¨ Metalloids (color your table)

Characteristics of Metals A. Metals 1. 2. 3. 4. They are solid They are shiny Good conductors of electricity They are ductile a. Can be rolled into thin wires 5. They are malleable a. Hammered into thin sheets 6. They lose electrons easily

Characteristics of Nonmetals A. Nonmetals 1. 2. 3. 4. 5. 6. 7. Are brittle (break easy) Are not shiny Is an invisible gas Not malleable Not ductile Poor conductors of electricity Tend to gain electrons

Characteristics of Metalloids A. Metalloids 1. Have characteristics of both metals and nonmetals a. Some are shiny, some are dull b. Are semiconductors a. Conduct electricity but not well c. Not as brittle as nonmetals
