Question

Compare the important characteristic of metals and non-metals

Answer 1

Metals
-Metals refers to the natural elements that are hard, shiny, opaque and dense.
•Electropositive
•Crystalline
•Solid (except mercury and gallium)
•High density
•Lustrous
•Most metals are hard, except sodium.
•Malleable
•Ductile
•Sonorous
•good conductor of heat and electricity
•Very high melting and boiling point.
•1 to 3 electrons in the outer shell
•React with oxygen and form basic oxides.
•React 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
•non lustrous
•Most non metals are soft, except diamond.
•Non-malleable
•non ductile
•non sonorous
•Poor conductor of heat and electricity
•low melting and boiling point
•4 to 8 electrons in the outer shell.
•React with oxygen and form acidic oxides.
•do not usually react with acid
