Explanation:
metal
Lustrous (shiny)
Good conductors of heat and electricity
High melting point
High density (heavy for their size)
Malleable (can be hammered)
Ductile (can be drawn into wires)
Usually solid at room temperature (an exception is mercury)
Opaque as a thin sheet (can't see through metals)
Metals are sonorous or make a bell-like sound when struck
non metalNot lustrous (dull appearance)
Poor conductors of heat and electricity
Nonductile solids
Brittle solids
May be solids, liquids or gases at room temperature
Transparent as a thin sheet
Nonmetals are not sonorous
