Energy levels and sub-levels Energy levels These are broadly similar to the “shells” used in GCSE Chemistry You need to know about energy levels 1, 2, 3 and 4 at A Level Energy level 1 is lowest in energy and closest to the nucleus

Energy levels and sub-levels Sub-levels The main energy levels contain sub-levels The different main energy levels have different sub-levels in them There are four types: s, p, d, f
