Lesson: Electron Shells Chemistry • 7th Grade

Students will be able to

• recall how the arrangement of the periodic table relates to the maximum number of electrons found in each shell,
• use the electron-shell model to assign a simple electron-shell configuration to an atom or ion,
• interpret shell diagrams in order to identify potential atoms and ions,
• explain the relative stability of the shells in order to correctly fill electron shells with electrons in the correct order.
