The document discusses metals, nonmetals, and metalloids according to their placement on the periodic table. Metals are located on the left side of the zigzag line, nonmetals are on the right side, and metalloids are along the zigzag line. Metals are malleable, ductile, good conductors while nonmetals are brittle, poor conductors. Metalloids exhibit properties between metals and nonmetals.

4. Properties of Metals, Nonmetals,
and Metalloids
METALS
malleable, lustrous, ductile, good conductors of heat
and electricity
NONMETALS
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. 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.

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 pressure

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
nonmetals
