Revision notes:

Section 1: Group 0

Group 0 elements are called noble gases. They are a very interesting group because all of the elements within it have full outer shells. Remember, it is the goal of atoms to have full outer shells. Because noble gases already have full outer shells, they do not react. We call them inert – this is because they more or less do not react at all. At room temperature, they are all colour gases that are monoatomic (single atoms that are not bonded to anything else).

Section 2: Boiling Points

You need to be able to recall that the boiling point increases as you go down group 0. This is called a trend. You may be asked to predict the boiling point of an element in group 0 based on information given.

Worked Example: The boiling point of neon is -246oC and krypton is -153 oC. What is the boiling point of argon.

We know that the boiling point increases as you go down the group. Argon is below neon and will therefore have a higher boiling than -246 oC. It is above krypton and will therefore have a lower boiling point than -153oC. The answer will therefore be somewhere in between -246 and -153.
