Define metal and non-metal, characteristics of metal

 Metals and Non-Metals:

  • Metals and non-metals are two classes of chemical elements.
  • Metals are elements that have properties such as good electrical conductivity, high thermal conductivity, and malleability, while non-metals have poor electrical conductivity and are usually poor conductors of heat. 
  • Some common metals include iron, aluminum, gold, silver, and copper. Some examples of non-metals include carbon, nitrogen, oxygen, and chlorine.
metal vs non metal


Characteristics of Metals:

  • -Metals have high luster or shine
  • -They are good conductors of heat and electricity
  • -They have a high melting and boiling point
  • -They are malleable, meaning they can be bent or shaped without breaking
  • -They are ductile, meaning they can be stretched or pulled into wires
  • -Most metals are solids at room temperature
  • -They tend to lose electrons when bonding with other elements to form positive ions
