1. Metal, Nonmetals and Metalloids

2. What are the physical properties of metals?
Most elements are metals
Physical Properties
Silver- grey in color
Luster (shininess)
Solid at room temperature
Good conductors of heat and electricity
What are the physical properties of metals?
chromium

3. Metals Can be drawn into wire- ductile
High density-heavy for their size
High melting and boiling point
Malleable (can be hammered into thin sheets)
May be magnetic
Have a characteristic sound when struck with an object (sonorous)
Metals
potassium

4. What are the physical properties of nonmetals?
Exist as solids, liquids, or gases at room temperature
Do not reflect light well
Are usually brittle
Cannot be hammered flat
Cannot be drawn into wire
Generally are soft and bend or break easily
Doesn’t have a characteristic sound when struck with an object
What are the physical properties of nonmetals?

5. Nonmetals Generally have low melting points
Generally have low boiling points
Are poor conductors of heat and electricity
Low densities-light for their size
Are not magnetic
Nonmetals
sulfur

6. Metalloids Physical Properties: Solids Can be shiny or dull
Can be ductile or malleable
Can be brittle
Conduct heat better than nonmetals, but not as well as metals
Reactivity depends on the element with which they are reacting
Melting and boiling point vary widely
Density varies widely

7. Periodic Table

8. Periodic Table The periodic table contains a zigzag line.
Elements on both sides of the line have properties of both metals and nonmetals.
Metals are located on the left side of the periodic table.
Nonmetals are located on the right side of the table
