Q
What group 0 known as
A
Noble gases
2
Q
Why don’t they react a lot
A
They have eight electrons in their outer shell apart from helium which has 2 giving them a full outer shell
As their outer shell is energetically stable they don’t need to gain or lose electrons to become stable
3
Q
What is the trend in the properties of the noble gases as you go down
A
The boiling points increase: increase in the number of electrons in each atom leading to greater intermolecular forces which need to be overcome
Increasing relative atomic mass
