Noble gases (Group 0)

• The noble gases all have low boiling points.
• Boiling point increases going down the group.
• Group 0 are called noble gases and are non metals
• They exist as single atoms
• when you go down the group the atoms become larger, the intermolecular forces between the atoms become stronger and more energy is needed to overcome these forces
• Noble gases have low densities
• The density in the group increases when you go down the group
