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 floatBoiling Point – Temp where it changes from liquid to gasConductivity – Ability to conduct heat, sound or electricityDensity –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 scratchedLuster- How it reflects lightMagnetism – Ability to attract ironMalleability – Ability to be pressed or pounded into thin sheetsMass – Amount of matter in an objectMelting point – Temp where a substance changes from a solid to a liquid.
4 OdorSolubility – Ability of a substance to dissolveState of Matter – Solid, liquid or gasTemperature – Amount of energy in matterVolume – 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 conductorNonmetal- element that is not shiny, ductile, malleable and is not a good conductorMetalloid – an element that has properties of both metals and non metals.Zig zag line (stair step) on periodic table separates the metals and nonmetals6 elements that border the zig zag are metalloids
7 Metals Non metals Metalloids Shiny Mostly dull Varying ability to conduct electricityMalleable (can be flattened into sheets)Brittle, not malleable or ductileCan be used to make semiconductors – conduct electricity only under certain conditions.Ductile (can be shaped into wires)Poor conductors of heat & electricityGood conductors of heat & electricityMany are gases at room temp.Most are solid at room temp.
