Non-Metals: Non-Metals are those elements which have tendency to gain electrons to form anions. Thus non-metals are called electronegative in nature. They are generally soft and bad conductors of electricity.
Semi-Metals or Metalloids: Semi-metals or metalloids are those elements which behave like both metals and non-metals.
