Key Concepts

Electron Configuration

Electron configuration is a method of representing the arrangement of electrons in an atom's orbitals. It shows how electrons are distributed across various energy levels and orbitals, which is key to understanding the chemical properties and reactivity of elements.

Ground-State

The ground state of an atom refers to the lowest energy configuration of electrons. In this state, electrons occupy the lowest available energy orbitals, making the atom as stable as possible under normal conditions.

Aufbau Principle

The Aufbau principle guides the order in which electrons fill orbitals. According to this principle, electrons populate orbitals starting from the lowest energy level and move to higher levels only when the lower ones are fully occupied.

Pauli Exclusion Principle

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers. This creates a limit on how many electrons can occupy a given orbital, typically allowing a maximum of two electrons with opposite spins.

Hund's Rule

Hund's rule states that electrons will fill degenerate (equal-energy) orbitals singly and with parallel spins rather than pairing up immediately. This minimizes electron-electron repulsion and results in a more stable electron configuration.

Atomic Orbitals

Atomic orbitals are regions around an atom's nucleus where electrons are likely to be found. They are defined by quantum numbers and come in various shapes and sizes, such as s, p, d, and f orbitals, which determine how electrons are arranged in an atom.
