  4. 4. Properties of Metals, Nonmetals, and MetalloidsMETALS malleable, lustrous, ductile, good conductors of heat and electricityNONMETALS gases or brittle solids at room temperature, poor conductors of heat and electricity (insulators)METALLOIDS (Semi-metals) dull, brittle, semi-conductors (used in computer chips)
  5. 5. Metals, Nonmetals, and Semimetals • The heavy orange zigzag line running diagonally from the upper left to the lower right through Groups 13–16 divides the elements into metals ( in blue, below and to the left of the line) and nonmetals (in bronze, above and to the right). • Elements colored in gold that lie along the diagonal line are semimetals and exhibit properties intermediate between metals and nonmetals.Copyright © 2007 Pearson Benjamin Cummings.

  6. 6. Metals, Nonmetals, and Semimetals • Metals - Good conductors of electricity and heat - Ductile - Malleable - Lustrous - In chemical reactions, metals lose electrons to form positively charged ions - Vast majority of known elements are metals - All are solids except for mercury, which is a liquid at room temperature and pressureCopyright © 2007 Pearson Benjamin Cummings.

  7. 7. Metals, Nonmetals, and Semimetals • Nonmetals - Poor conductors of heat and electricity - Not lustrous - Can be gases, liquids, or solids - Solid nonmetals are brittle - Tend to gain electrons in reactions with metals to form negatively charged ions - Share electrons in reactions with other nonmetals • Semimetals - Exhibit properties intermediate between metals and nonmetalsCopyright © 2007 Pearson Benjamin Cummings.
