Orbital Diagrams, Rules and Principles

Front

What is the Aufbau principle?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first before filling higher energy orbitals.

Front

What does Hund's rule state?

Back

Hund's rule states that every orbital in a given subshell is singly occupied before any orbital is doubly occupied, and all singly occupied orbitals have the same spin.

Front

What is the Pauli exclusion principle?

Back

The Pauli exclusion principle states that no two electrons in an atom can have the same set of four quantum numbers, meaning that an orbital can hold a maximum of two electrons with opposite spins.

Front

What is an orbital diagram?

Back

An orbital diagram is a visual representation of the arrangement of electrons in an atom's orbitals, showing the distribution of electrons among the various orbitals.

Front

What does the term 'subshell' refer to?

Back

A subshell is a division of electron shells that contains one or more orbitals, characterized by the angular momentum quantum number (s, p, d, f).

Front

How many electrons can the s subshell hold?

Back

The s subshell can hold a maximum of 2 electrons.

Front

How many orbitals are in the p subshell?

Back

The p subshell contains 3 orbitals.

Front

What is the maximum number of electrons that can occupy the d subshell?

Back

The d subshell can hold a maximum of 10 electrons.

Front

What is the significance of the quantum numbers?

Back

Quantum numbers describe the properties of atomic orbitals and the electrons in those orbitals, including their energy level, shape, orientation, and spin.

Front

What is the difference between an electron configuration and an orbital diagram?

Back

An electron configuration is a notation that shows the distribution of electrons among the orbitals, while an orbital diagram visually represents the same information using boxes and arrows.
