4
Q
Describe the electrons in a noble gas

5
Q
Describe the structure of a noble gas
A
Monatomic - Single atoms with very weak forces of attraction between them
These forces are easily overcome by heat giving them very low boiling points
6
Q
What happens going down group 0
A
The attractive forces between atom gets stronger
The boiling point increases
Density increases
