Play a game to memorize the order in which orbitals fill. Have each group member in turn state the name of the next orbital to fill and the maximum number of electrons it can hold (for example, e, "1$s$ two," "2$s$ two," "2$p$ six," etc.). If a member gets stuck, other group members can help, consulting Figure 8.5 and the accompanying text summary if necessary. However, when a member gets stuck, the next player starts back at "1$s$ two." Keep going until each group member can list all the orbitals in order up to "6$s$ two."

Key Concepts

Electron Configuration

Electron configuration is the arrangement of electrons within the orbitals of an atom. It describes how electrons are distributed among the various energy levels and subshells, providing insight into an element's chemical properties and behavior.

Aufbau Principle

The Aufbau Principle is a guideline that electrons occupy the lowest available energy orbitals first before filling higher energy orbitals. This principle explains the order in which orbitals are populated in an atom, from the 1s orbital upward.

Orbital Capacity

Each type of orbital (designated as s, p, d, f, etc.) has a specific maximum number of electrons it can contain. For example, s orbitals can hold up to 2 electrons, while p orbitals can hold up to 6. This capacity is determined by the quantum mechanical properties of the orbitals.

Spectroscopic Notation

Spectroscopic notation is a shorthand method for writing electron configurations. It involves using a number to indicate the principal energy level followed by a letter representing the type of orbital (s, p, d, f) and a superscript that specifies the number of electrons in that orbital.
