Physical Properties

metals, non-metals, metalloids and density review

TermDefinition
physical properties measurable characteristics that describe the physical state of something; includes mass, magnetism, temperature, density, luster and conductivity
metals elements to the right side of the stair step line on the Periodic Table; typically solid, shiny, malleable, and good conductors of heat and electricity
non-metals elements to the left side of the stair step line on the Periodic Table; typically dull, brittle, and poor conductors of heat and electricity
metalloids elements along the stair step line on the Periodic Table; have properties of both metals and non-metals; also called semi-conductors
luster how a material reflects light; shiny objects reflect a lot of light; dull objects do not reflect much light
conductivity the ability of a substance to transfer heat or electrical energy
malleability the ability of something to be shaped without breaking; example - aluminum foil
ductility the ability of something to be pulled into a wire
brittle breaks easily
poor conductor a material that does not transfer heat or electrical energy very well
good conductor a material that easily transfers heat or electrical energy
semi-conductor a material that transfers heat and electrical energy better than a non-metal but not as well as a metal; the foundation of modern electronics
matter anything that has mass and takes up space
density the relationship between mass and volume; calculated using the formula D = m/v
volume the amount of space an object occupies; for a rectangular prism calculated V = lwh
displacement a method for calculating the volume of oddly shaped objects using a graduated cylinder and water
