1. Physical Properties Notes
(6.6) The student knows matter has physical properties that can be used for classification.
Compare metals, nonmetals, and metalloids using physical properties such as luster, conductivity, or malleability

2. Physical Properties Appearance – Color, size, shape, texture
Buoyancy – Tendency to float
Boiling Point – Temp where it changes from liquid to gas
Conductivity – Ability to conduct heat, sound or electricity
Density –Amount of matter in a given volume D=m/v

3. Ductility – Ability of a substance to be pulled into a thin strand, such as wire.
Hardness – Ability to resist being scratched
Luster- How it reflects light
Magnetism – Ability to attract iron
Malleability – Ability to be pressed or pounded into thin sheets
Mass – Amount of matter in an object
Melting point – Temp where a substance changes from a solid to a liquid.

4. Odor
Solubility – Ability of a substance to dissolve
State of Matter – Solid, liquid or gas
Temperature – Amount of energy in matter
Volume – Amount of space an object takes up.

5. Metals, Nonmetals, & Metalloids
Elements are classified as metals, nonmetals, and metalloids based on their properties.
Metal – element that is shiny, ductile, malleable and a good conductor
Nonmetal- element that is not shiny, ductile, malleable and is not a good conductor
Metalloid – an element that has properties of both metals and non metals.
Zig zag line (stair step) on periodic table separates the metals and nonmetals
6 elements that border the zig zag are metalloids

7. Metals Non metals Metalloids Shiny Mostly dull
Varying ability to conduct electricity
Malleable (can be flattened into sheets)
Brittle, not malleable or ductile
Can be used to make semiconductors – conduct electricity only under certain conditions.
Ductile (can be shaped into wires)
Poor conductors of heat & electricity
Good conductors of heat & electricity
Many are gases at room temp.
Most are solid at room temp.
