Electron Configurations & Orbital Notation

Front

What is an electron configuration?

Back

An electron configuration is the distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What does the notation 1s² represent?

Back

The notation 1s² indicates that there are 2 electrons in the 1s orbital, which is the lowest energy level.

Front

How many electrons can the s sublevel hold?

Back

The s sublevel can hold a maximum of 2 electrons.

Front

What is the maximum number of electrons that can occupy the p sublevel?

Back

The p sublevel can hold a maximum of 6 electrons.

Front

What is the significance of the Aufbau principle in electron configurations?

Back

The Aufbau principle states that electrons fill orbitals starting from the lowest energy level to the highest.

Front

What is Hund's rule?

Back

Hund's rule states that electrons will occupy degenerate orbitals singly before pairing up to minimize repulsion.
