Open original (opens in a new tab)Understand the arrangement.
Explore how electrons are organized into shells, subshells, and orbitals, then connect that arrangement to an element’s place in the periodic table.
- Distinguish a shell, a subshell, and an orbital.
- Write a ground-state electron configuration for a main-group atom.
- Identify core and valence electrons.
Try it as you studyCount the electrons in each configuration you write. Does the total match the atomic number?

How scoring works
Selections are kept when you move between questions. Finish grades any remaining selections; unanswered questions count as incorrect. Retries help you learn without changing your first score. Finished results go to My progress; unfinished answers stay in this session.
