Properties of Metals, Nonmetals, and Metalloids : Properties of Metals, Nonmetals, and Metalloids METALS NONMETALS METALLOIDS malleable, lustrous, ductile, good conductors of heat and electricity gases or brittle solids at room temperature, poor
conductors of heat and electricity (insulators) (Semi-metals) dull, brittle, semi-conductors (used in computer chips)
Slide 5 : 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. Metals, Nonmetals, and Semimetals Copyright © 2007 Pearson Benjamin Cummings. All rights reserved.
Slide 6 : 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 pressure Metals, Nonmetals, and Semimetals Copyright © 2007 Pearson Benjamin Cummings. All rights reserved.
Slide 7 : 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 nonmetals Metals, Nonmetals, and Semimetals Copyright © 2007 Pearson Benjamin Cummings. All rights reserved.
