Who? For those teaching the new Chemistry/ Combined Science GCSE (2016). Also for those of you requiring a clear and simple worksheet for your students to complete on the first 20 elements of the periodic table.
What? This worksheet requires students to look up each element (from the top 20) in the periodic table to deduce how many electrons. They will then need to apply the 2, 8, 8 rule and away they go!
A couple of bonus questions at the end… (Answers are on included on the second sheet - all electronic configurations given to save you looking them up!)
