Metals+vs+Nonmetals

Usually have 1-3 electrons in their outer shell.

Lose their valence electrons easily.

Form oxides that are basic.

Are good reducing agents.

Have lower electronegativities. Usually have 4-8 electrons in their outer shell.

Gain or share valence electrons easily.

Form oxides that are acidic.

Are good oxidizing agents.

Have higher electronegativities. Good electrical conductors and heat conductors.

Malleable - can be beaten into thin sheets.

Ductile - can be stretched into wire.

Possess metallic luster.

Opaque as thin sheet.

Solid at room temperature (except Hg). Poor conductors of heat and electricity.

Brittle - if a solid.

Nonductile.

Do not possess metallic luster.

Transparent as a thin sheet.

Solids, liquids or gases at room temperature.
