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.
