1. What is Electron Configuration?

Electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. It describes how electrons are arranged around the nucleus of an atom.

2. How Does the Calculator Work?

The calculator analyzes the electron configuration input and determines the corresponding element:

Where:

• Total Electrons — Sum of all superscript numbers in the configuration
• f — Mapping function to periodic table

Explanation: Each element has a unique electron configuration that corresponds to its atomic number (number of protons/electrons).

3. Importance of Electron Configuration

Details: Electron configuration determines an element's chemical properties, including its reactivity, bonding behavior, and position in the periodic table.

4. Using the Calculator

Tips: Enter the electron configuration in standard notation (e.g., 1s² 2s² 2p⁶). The calculator will identify the element based on the total number of electrons.

5. Frequently Asked Questions (FAQ)

Q1: What's the format for electron configuration?
A: Use standard notation with spaces between orbitals (e.g., 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶).

Q2: How accurate is this calculator?
A: It works for neutral atoms in their ground state. Excited states or ions may require special notation.

Q3: What about exceptions to the Aufbau principle?
A: Some elements (like Cr, Cu) have exceptions. For these, you may need to input the actual configuration.

Q4: Can this calculator work backwards?
A: Yes, you can input an element name/symbol to get its electron configuration (not implemented in this version).

Q5: What's the maximum number of electrons per orbital?
A: s=2, p=6, d=10, f=14 electrons following the Pauli exclusion principle.
