What is the Electron Configuration Calculator?

The Electron Configuration Calculator determines the electron arrangement of an atom based on its atomic number (Z). By applying the Aufbau principle, Hund’s rule, and the Pauli exclusion principle, it assigns electrons to the appropriate subshells (s, p, d, f) and displays the full electron configuration in standard notation. This tool helps students, teachers, and chemists quickly determine electron distributions for elements, which is essential for understanding chemical behavior, bonding, and periodic trends.

How to Use:

1. Enter Atomic Number (Z): Type the atomic number of the element.
2. Click “Calculate”: The calculator fills the electron subshells according to the standard filling order.
3. Review the Result: The electron configuration will appear in subshell notation with superscripted electron counts, providing a clear representation of the atom’s electron distribution.
