1
Q
What group is typically inert?

The noble gases, group 0/8.
2
Q
What group consists of only monatomic atoms?
A
The noble gases, group 0/8.
3
Q
What are the properties of noble gases?
A
Inert,
Low density,
Low boiling point.
4
Q
What group consists of only diatomic molecules?
A
The halogens, group 7.
5
Q
Why do halogens decrease in reactivity as you go down the group?
A
Electron shielding.
The attraction between electrons and the nucleus is weaker if they are further away.
6
Q
What happens in a halogen displacement reaction?
A
