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
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
• Ductility – Ability of a substance to be
pulled into a thin strand, such as wire.
• Hardness – Ability to resist being
• 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.
• Odor
• Solubility – Ability of a substance to
• State of Matter – Solid, liquid or gas
• Temperature – Amount of energy in matter
• Volume – Amount of space an object
takes up.
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
Non metals
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
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
