Electron Configurations - Filling shells, sub-shells and orbitals

Activity to assess understanding of the filling of energy levels, electron shells, sub-shells and orbitals to derive electron configurations.

Structured worksheets provide students with the opportunity to fill in energy level diagrams and ‘electrons in boxes’ diagrams to facilitate derivation of the overall electron configuration for the first 36 elements (hydrogen - krypton).

Resource contains:

Worksheet set 1 - diagrams/configurations for completion for 36 elements, 4 elements to a page, set in order of atomic number (9 pages total)

Worksheet designed for ease of printing - could be printed and cut out (guide lines provided) to give students specific examples to complete - mini task cards!

Worksheet set 2 - diagrams/configurations for completion for 20 randomly selected elements, 4 elements to a page, in order of increasing difficulty (5 pages total).
