A Level Chemistry Revision "First Ionisation Energy down a Group"

You can find all my A Level Chemistry videos fully indexed at https://www.freesciencelessons.co.uk/... In this video, we look at how the first ionisation energy varies as we move down a group in the periodic table. We look at this in terms of atomic radius, nuclear shielding and the nuclear charge. This is a very common exam question, so it's worth learning. This video is aimed at the UK A Level Chemistry specifications. Students studying International A Level Chemistry will need to check their specification.
