Group 0 Elements

• Group 0 Elements


  All Unreactive, Colourless Gases
• Group 0 elements


  The noble gases
• Noble gases


  • helium
  • neon
  • argon
  • plus a few others
• All elements in Group 0 are colourless gases at room temperature
• Group 0 elements


  • They all have eight outer shell electrons, apart from helium which has two
  • This means they have a stable full outer shell
  • This stability makes them very unreactive (inert)
  • They don't form molecules easily, so the elements are single atoms
• Some reactions are carried out in an atmosphere that only contains a noble gas, instead of air
• As you go down Group 0


  • The relative atomic masses of the elements increase
  • The elements have more electrons
  • More electrons means stronger forces between atoms
  • The stronger the forces, the higher the boiling point
  • The boiling points increase
• Noble gases


  • helium
  • neon
  • argon
  • krypton
  • xenon
  • radon
• If you're given the boiling point of one noble gas you can predict the boiling point for another one
