Group 0

• The noble gases are very unreactive elements
• all of the noble gases have a full outer shell which makes them unreactive
• the boiling points of the noble gases increases as the relative atomic mass increases
• all elements in group 0 are colourless gases at room temperature
• the increase in boiling point is due to an increase in the number of electrons in each atom leading to greater intermolecular forces between them which need to be overcome
