Lesson Plan: Electronic Configurations Chemistry • 10th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to use electron-shell notation to identify elements and describe the electronic configurations of atoms and ions.


Students will be able to

  • link ideas of electron shells to electronic configuration,
  • describe the number and composition of electronic orbitals within the principle quantum numbers,
  • describe the relative energy levels and composition of the principal quantum numbers and orbitals,
  • use the rules governing the order in which electrons fill and are lost from orbitals.


Students should already be familiar with

  • the structure of the atom and nuclide notation,
  • formation of ions,
  • simple electronic configurations and the concept of electron shells/levels.


Students will not cover

  • potential anomalies in the filling of orbitals for transition metals,
  • the shapes of d and f orbitals,
  • filling patterns beyond the fourth quantum number.
