Chemistry 1.4 Successive ionisation energies 0.0 / 5 ? ChemistryThe Periodic TableASWJEC Created by: DanCreated on: 26-12-13 12:58 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 6 of 6
