Group 0: the noble gasesFree4:12Heddy Score 3 of 7, below the standard
What you need to know
- Noble gases are very unreactive because their outer electron shells are full.
- Their boiling points increase down the group.
- Helium’s low density and lack of flammability make it useful for balloons.
- UK GCSE calls this column Group 0; the title’s “Group 18” is the same group under its international name.
