1
Q
Why are group 0 elements unreactive?
A
Because they have a full outer shell
They cannot gain electrons from other elements to react
2
Q
Why do group 0 elements have low boiling points?
A
Because they are all gases
3
Q
What is the trend of the boiling points in group 0?
A
The boiling points increase as the relative atomic masses increase (ie going down the table)
