Metals, non-metals, metalloids Physical Properties Metals, non-metals, metalloids

In class 9-11-12 Obj. I am expected to compare metals, non-metals, and metalloids using their physical properties such as luster, conductivity, and malleability. Vocabulary Luster Malleability Conductivity Magnetism Ductile Metals Non-metals Metalloids

Luster the way it reflects light or shines

malleability The ability to be hammered in to a thin sheet or into most shapes.

conductivity How well it allows heat and electricity to pass through it

ductile Can be stretched or rolled into a wire

magnetism Being attracted or not attracted to a magnet.

metals A substance that is shiny, malleable, hard, and a good conductor of heat and electricity.

Non metals A substance that is brittle, not malleable, may be a gas, and a poor conductor of heat and electricity.

Metalloid An element that share properties of metals and non metals, they are semi- conductors.
