Metals and non metals

• Metals

  • Most elements are Metals
  • They are towards the bottom end of the periodic table
• Non-Metals


  • They are at the top and far right of the periodic table
• Metals


  React faster when they act
• Electronic Structure of Atoms

  Affects How They Will React
• Atoms reacting

  1. Form a full outer shell

  2. Do this by losing, gaining or sharing electrons
• Elements to the left of the periodic table

  Have many outer electrons and tend to form positive ions
• Elements to the right of the periodic table

  Have few outer electrons and tend to form negative ions
• Metals

  • Have metallic bonding
  • Hard to break
  • Can be bent or based into different shapes (malleable)
  • Good conductors of heat and electricity
  • Have high boiling and melting points
• Non-Metals

  • Don't have metallic bonding
  • Tend to be dull looking
  • Many are gases at room temperature
  • Don't generally conduct electricity
  • Often have a low density
