Differences between metals & non-metals Metals Non-metals Most are solids at room temperature (except mercury) Most are solids of low melting points, liquids or gases Most have a lustrous surface Most lack a lustrous surface Malleable and ductile Non-malleable and brittle Good conductors of heat and electricity Poor conductors of heat and electricity (except graphite) Lose electrons to form positive ions (cation) Gain electrons to form negative ions (anion) Oxides are basic (e.g. CaO) Oxides are acidic (e.g. SO 2 )
