1what is the name of group 0 atoms
2how many electrons in the outer shell of group 0 atoms
3do group zero atoms exist as single or double atoms, and why?
4why does group 0 atoms have low boiling points
have weak inter molecular forces, that do not require much energy to break
5why does boiling point decrease down group 0 (examiners answer- 4 marks)
6chemical properties of group 0 atoms
they are inert - because they have a full outer shell meaning they are extremely stable.
