Allocate each student one element from H to Ca (there may be duplicates). Students organise the sheets on the floor into atomic number order (as in the periodic table). Outside, chalk four circles on the ground to represent shells. Each student represents electrons (the teacher or a student could represent the nucleus). Starting with the inner circle, the students occupy each circle following rules for electronic configurations. Extra students in a large class may be used to call out or record the identities
