Answer:
metals tend to lose their valence electrons, but non-metals share or gain valence electrons. ... While metals are good conductors of electricity and heat, non-metals are poor conductors. Unlike non-metals, metals are ductile, which means they can be stretched into wires.

Answer: Metals : Metals refers to the natural elements that are hard, shiny, opaque and dense. They are electropositive. Structure-crystalline. Physical state - solid (except mercury and gallium). High density. Lustrous. Most metals are hard except sodium. Malleable, ductile, sonorous, good conductor of electricity, very high melting and boiling point, 1 to 3 electrons in the outer shell, react with oxygen and forms basic oxides. Reacts with acids and produce hydrogen gas.
Non-Metals : Non-Metals implies those chemical substances that are soft, non-shiny, transparent and brittle. Electronegative. Amorphic. Solid or gas (except bromine). Low density.
Hope you are clear.
