Build Your Electron Configuration Map
Turn lecture notes or a chapter PDF into a branching map of atomic structure you can expand and revise.
Map from your own notes
Upload a PDF, Word file, slides or image of your chemistry notes and get a structured map automatically.
Clear structure for orbitals
Branches separate shells, subshells, orbital shapes and electron capacity so the rules stay organized.

Electron Configuration Mind Map Essentials
An electron configuration describes how electrons are arranged in an atom's orbitals. It follows from three core rules: the Aufbau principle, which fills lower energy orbitals first; the Pauli exclusion principle, which allows at most two electrons per orbital with opposite spins; and Hund's rule, which spreads electrons across orbitals of equal energy before pairing them.
- Energy levels: principal shells numbered n = 1, 2, 3 and so on.
- Subshells: s, p, d and f, each with a fixed electron capacity.
- Orbitals: spatial regions holding a maximum of two electrons each.
- Filling order: the diagonal rule and common exceptions such as chromium and copper.
- Notation: shorthand using noble gas cores, such as [Ne]3s2 3p5.
Use a map like this to revise filling order, check exceptions, and practice writing configurations. Build one from your own lecture notes with CogniGuide to match your course.

Electron Configuration Questions
Common questions about electron configurations and how to map them.
What is the Aufbau principle?
The Aufbau principle states that electrons occupy the lowest energy orbitals available before filling higher ones. It is the basis for predicting the order in which subshells fill, usually shown with the diagonal rule.
Why do some elements break the expected filling order?
Chromium and copper are common exceptions. A half-filled or fully filled d subshell has extra stability, so one electron shifts from the 4s orbital into a 3d orbital.
Which files can I use to make my own electron configuration map?
You can upload a PDF, Word document, PowerPoint file, text or Markdown file, or an image of your notes. You can also just type the topic to start.
Is it free to create a map and turn it into a quiz?
There is a free plan with 5 creations a week and no payment needed. Paid plans raise the limits, and each map can be turned into a quiz to test yourself.
