What is meant by 'successive ionisation'?
The amount of energy needed to remove each electron in turn until all the electrons are removed from an atom
1 of 6
Sodium has 11 electrons. What is the maximum number of ionisation energies it has?
11
2 of 6
Describe what happens as more and more electrons are removed.
Less electronic repulsion occurs drawing the electronic shell closer to the nucleus
3 of 6
If the electronic shells get closer to the nucleus, what increases?
Nuclear attraction
4 of 6
What does a large increase in successive ionisation energy show?
An electron has been removed from a new shell closer to the nucleus and gives the group to which the element belongs
5 of 6
If Aluminium has a large ionisation energy jump between the 3rd and 4th IE, what group does Aluminium belong to?
Group 3
