AS Level Chemistry - Unit 1.4 Ionisation energy

**This Powerpoint specifically uses the Cambridge AS Level Chemistry Syllabus (9701) and covers all criteria for – Unit 1.4 Ionisation energy
**

Students will be able to

1 define and use the term first ionisation energy, IE

2 construct equations to represent first, second and subsequent ionisation energies

3 identify and explain the trends in ionisation energies across a period and down a group of the Periodic Table

4 identify and explain the variation in successive ionisation energies of an element

5 understand that ionisation energies are due to the attraction between the nucleus and the outer electron

6 explain the factors influencing the ionisation energies of elements in terms of nuclear charge, atomic/ionic radius, shielding by inner shells and sub-shells and spin-pair repulsion

7 deduce the electronic configurations of elements using successive ionisation energy data

8 deduce the position of an element in the Periodic Table using successive ionisation energy data

**Every Powerpoint includes learning objectives, a starter and plenary, suitable activities and review questions with mark scheme. We also provide a free pdf version of the file so it can easily be printed for students as a handout or uploaded to the school VLE system
