Physical Properties of Metals

● Hard and have a high tensile strength
● Solid at room temperature
● Sonorous
● Good conductors of heat and electricity
● Malleable, i.e., can be beaten into thin sheets
● Ductile, i.e., can be drawn into thin wires
● High melting and boiling points (except Caesium (Cs) and Gallium (Ga))
● Dense, (except alkali metals). Osmium – highest density and lithium – least density
● Lustrous
● Silver-grey in colour, (except gold and copper)

Physical Properties of Nonmetals

• Occur as solids, liquids and gases at room temperature
• Brittle
• Non-malleable
• Non-ductile
• Non-sonorous
• Bad conductors of heat and electricity

• Chemical Properties of Metals

  ● Alkali metals (Li, Na, K, etc) react vigorously with water and oxygen or air.
  ● Mg reacts with hot water.
  ● Al, Fe and Zn react with steam.
  ● Cu, Ag, Pt, Au do not react with water or dilute acids.
