Electron Configurations and Orbital Notation

Front

What is Hund's Rule?

Back

Hund's Rule states that all orbitals of equal energy are occupied by one electron before any single orbital is occupied by a second electron.

How many electrons can the p sublevel hold?

Back

The p sublevel can hold a maximum of 6 electrons.

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.

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 is noble-gas notation?

Back

Noble-gas notation is a shorthand way of writing electron configurations using the electron configuration of the nearest noble gas.
