Physical properties of metals:-1)Shiny (lustrous)2)Good conductors of electricity and heat 3)High density 4)High melting point 5)Malleable 6)Ductile and so can be drawn into wires 7)Solid at room temperature except for mercury 8)Opaque objects
Physical properties of non-metals:-1)Poor conductors of electricity and heat 2)Non-Ductile metals 3)Brittle solids 4)May be solids, liquids or gases at room temperature 5)These are not sonorous.
Chemical properties of metals:-1)Easily corrodible 2)Can lose electrons 3)Form basic oxides 4)Have lower electronegativities 4)Acts as very good reducing agents
Chemical properties of non-metals:-1)Generally, contain 4-8 electrons in the outer shell 2)Readily lose or gain valence electrons 3)Form acidic oxides 4)High electronegative elements 5)Great oxidizing agents
