Which are physical properties of most metals? (check all the correct answers)
most are solids
shiny, or lustrous
malleable (bendy) and ductile (stretchy)
conduct thermal and electrical energy
Which are physical properties of nonmetals? (check all the correct answers)
most are gases
the solid nonmetals (ex/ carbon, sulfur) are dull (not lustrous)
solids are brittle (crumble instead of bend)
insulate well, DON'T conduct thermal energy or electricity

metalloids are located along the "stair steps" between the metals and nonmetals
metalloids are shiny and metallic in color
metalloids are called "semiconductors" and don't conduct thermal energy and electricity as well as metals do
