A Level Chemistry Revision "Electron Configuration 2"

You can find all my A Level Chemistry videos fully indexed at https://www.freesciencelessons.co.uk/... In this video, we continue exploring how to assign electrons to the correct atomic orbitals. We look at how to deal with the 3d and 4s subshells before looking at two exceptions to the rules: chromium and copper. This video is aimed at the UK A Level Chemistry specifications. Students studying International A Level Chemistry will need to check their specification.
