## Overview

The Electron Configuration Calculator allows you to quickly look up the electron configurations, shell distributions, valence electrons, and orbital diagrams of any chemical element. Simply enter an element symbol or atomic number to retrieve detailed quantum state distributions and orbital structures.

## Inputs

- **Element Symbol or Atomic Number** (text): Fe or 26
- **Include Orbital Diagram** (checkbox)

## When to use

- When studying chemistry and needing to quickly find the shorthand or full electron configuration of an element.
- When verifying the number of valence electrons or shell distributions for chemical bonding analysis.
- When visualizing orbital diagrams to understand electron spin and subshell filling orders.

## How it works

- Enter the chemical element symbol or its atomic number into the input field.
- Toggle the option to include or exclude the orbital diagram representation.
- Submit the query to generate the full configuration, shell distribution, and valence electron count.

## Use cases

- Chemistry students completing homework assignments on atomic structure and electron configurations.
- Educators preparing lecture materials and visual orbital diagrams for chemistry classes.
- Researchers checking valence electron counts and subshell configurations for chemical reaction modeling.

## Frequently asked questions

### Can I search using both element names and atomic numbers?

You can search using element symbols (like Fe) or atomic numbers (like 26).

### What information does the calculator output?

It outputs the full electron configuration, shell distribution, valence electrons, and orbital diagrams.

### Does the calculator support noble gas shorthand notation?

Yes, it provides both the full configuration and the shorthand notation using noble gas cores.

### What is the orbital diagram option?

It shows the arrangement of electrons in individual orbitals, indicating their spin states.

### Can I use this for transition metals and lanthanides?

Yes, it calculates configurations for all standard elements, including transition metals and inner transition elements.
