Key Concepts

Quantum Numbers and Orbital Capacities

Quantum numbers describe the properties of electrons in orbitals, including their energy level, shape, and orientation. Each orbital has a specific capacity (such as 2 electrons for s orbitals, 6 electrons for p orbitals, and 10 electrons for d orbitals) that governs how electrons are arranged in an atom.

Periodic Table Trends and Noble Gas Notation

The periodic table organizes elements based on increasing atomic number and recurring chemical properties, which is closely related to their electron configurations. Noble gas shorthand is a convenient method used to express electron configurations; it involves writing the configuration by starting with the configuration of the nearest noble gas to simplify the notation.

Electron Configuration

Electron configuration is the process of arranging electrons in an atom’s available orbitals according to specific rules. It details how electrons are distributed among shells and subshells, reflecting the atomic structure and chemical behavior of an element.

Aufbau Principle

The Aufbau principle states that electrons fill atomic orbitals in order of increasing energy. This rule is used to predict the electron configuration of an element by starting from the lowest energy orbital and moving upward, ensuring that each electron occupies the most stable state available.
