  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
