Study Notes
Properties of Metals and Non-Metals
-
Metals:
- Solids at room temperature (melting and boiling points decrease moving down the group)
- Very reactive (reactivity increases moving down the group)
- Good conductors of heat and electricity
- Soft
- Shiny when cut
- Low density
-
Non-Metals:
- Dull
- Poor conductor of heat
- Poor conductor of electricity
- Not sonorous
- Oxides form acidic solutions
- Low density
- Brittle
Key Terms & Definitions
- Boiling Point: The temperature at which a substance changes from liquid to gas (evaporates) or from gas to liquid (condenses).
- Brittle: Hard but easily broken.
- Conduction: The transfer of heat or electricity through a material.
- Density: The mass of a substance divided by its volume. Higher density means heavier for its size.
- Displacement Reaction: A reaction in which a more reactive substance displaces a less reactive substance.
- Ductile: Can be stretched into wires.
- Dull: Not shiny.
- Magnetic Material: A type of material with the ability to become magnetized.
Pressure and Density
- Pressure increases with the amount of material (like water) above.
- Density affects whether something floats or sinks. If an object's density is less than the fluid's density, it will float. Water's density is 1 g/cm³.
- Drag: Air or water resistance. It increases with speed and smooth surfaces reduce it.
