About the Nobel Gases
- Group 0 used to be called Group 8 but this caused confusion because most elements in Group 8 have 8 electrons in their Outer Shell but Helium only has 2, so it was renamed Group 0.
- The Nobel Gases are all inert which means they do not react with other atoms.
- The Nobel Gases are all monatomic which means they exist only as single atoms and do not join to form any molecules.
The Nobel Gases in order of the number of electron shells:
Chemical Properties
- The Nobel Gases are all inert (unreactive) because they have a full outer shell.
Physical Properties
- The Nobel Gases are all gases at room temperature.
- The density and boiling point all increase as you go down the Periodic Table.
