• Metals shine and reflect light i.e metals are lustrous.
• Metals are hard substances , exceptions are Mercury and gallium which exist in liquid state.
• The materials which have a bright surface and reflect light are called lustrous materials and materials that do not shine are non-lustrous.
• Generally metals are lustrous.
• The property of material is called luster.
• Examples - Gold, Silver, Platinum, Copper etc .
• Metals have high densities.
• Metals have high melting and boiling point.
• Metals are good conductors of heat and electricity.
• Non-metals are non-lustrous.
• Metals produce ringing sound when they fall on hard surface i.e metals are sonorous.
• Metals can be flattened into thin sheets i.e metals are ductile. Exceptions are zinc, antimony, and arsenic , These metals are malleable.
