Reffer the achievement

Physical characteristics of metals:

• Almost all metals are solids (except mercury)
• They have high melting and boiling points. (except alkali metals)
• They poSsess metallic luster and can be polished
• They are malleable (can be hammered into sheets), ductile (can be drawn into wires) and give off a tone when hit.
• They are good conductor of heat and electricity.
• They have high densities.
• They are hard (except sodium and potassium)

Physical characteristics of non-metals:

• Non-metals are bad conductors of heat and electricity (except graphite).
• They are not shiny, they are dull except iodine (it is lustrous like metals).
• They are generally soft (except diamond)
• They have low melting and boiling points (except silicon, graphite and diamond).
• They have low densities.
