1. What is Electron Configuration?

Electron configuration describes the distribution of electrons in an atom's electron shells and subshells. It follows the Aufbau principle, Pauli exclusion principle, and Hund's rule. The configuration determines an element's chemical properties and reactivity.

2. How Does the Calculator Work?

The calculator determines the electron configuration by:

Identifying the element by symbol or atomic number
Adjusting the total electrons based on the specified charge
Filling orbitals following the standard order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, etc.
Calculating the maximum electron capacity for the neutral atom

3. Importance of Electron Configuration

Details: Electron configuration explains periodic trends, chemical bonding, and element reactivity. It's fundamental to understanding chemistry and predicting how elements will interact.

4. Using the Calculator

Tips: Enter either the element symbol (e.g., 'Fe') or atomic number (e.g., '26'). Specify the charge (-7 to +7). Positive charges remove electrons, negative charges add electrons.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between ground state and excited state configurations?
A: Ground state is the lowest energy configuration. Excited states have electrons promoted to higher orbitals.

Q2: Why do some elements have irregular configurations?
A: Some elements (like Cr and Cu) have half-filled or fully-filled d subshells for greater stability.

Q3: How does charge affect electron configuration?
A: Positive charges (cations) have fewer electrons, negative charges (anions) have more electrons than the neutral atom.

Q4: What are valence electrons?
A: Electrons in the outermost shell that participate in chemical bonding.

Q5: How accurate is this calculator?
A: It provides standard configurations but may not account for all exceptions in the transition metals and lanthanides/actinides.
