Electron Configuration and Aufbau Diagram

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

Define 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 does Pauli's Exclusion Principle state?

Back

Pauli's Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.

Front

How many electrons can fit in a p orbital?

Back

A p orbital can hold a maximum of 6 electrons.

Front

What is the maximum number of electrons in a d sublevel?

Back

The d sublevel can hold a maximum of 10 electrons.

Front

How many orbitals are in the f sublevel?

Back

The f sublevel contains 7 orbitals.

Front

What is the electron configuration for Oxygen (O)?

Back

The electron configuration for Oxygen is 1s² 2s² 2p⁴.

Front

What is the significance of the periodic table in electron configuration?

Back

The periodic table helps predict the electron configuration of elements based on their position, reflecting their atomic number and the filling order of orbitals.

Front

What is the shape of an s orbital?

Back

An s orbital has a spherical shape.

Front

Describe the shape of a p orbital.

Back

A p orbital has a dumbbell shape, with two lobes on either side of the nucleus.
