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 is the maximum number of electrons that can occupy the s sublevel?

Back

The s sublevel can hold a maximum of 2 electrons.

Front

How many orbitals are in the p sublevel?

Back

The p sublevel contains 3 orbitals.

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 Aufbau principle?

Back

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

Front

What is Hund's rule?

Back

Hund's rule states that electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

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 electron configuration for a nitrogen atom?

Back

The electron configuration for a nitrogen atom is 1s² 2s² 2p³.

Front

How many electrons can the first energy level hold?

Back

The first energy level can hold a maximum of 2 electrons.

Front

What is an orbital diagram?

Back

An orbital diagram is a visual representation of the arrangement of electrons in an atom's orbitals, using arrows to represent electrons.
