Group 0 elements

• What are group 0 elements known as?


  Noble gases.
• Noble gases are more stable due to them having a full outer shell, so they don’t need to lose or gain any electrons.
• What is the only noble gas without a full outer shell?


  Helium.
• Noble gases exist as monatomic gases- single atoms not bonded to eachother.
• What are noble gases at room temperature?


  Colourless gases.
• Noble gases are non-flammable.
• What happens to boiling points as you go down group 0?


  Increases.
• Why do boiling points increase as you go down group 0?


  More electrons in each atom so greater intermolecular forces.
