Orbital Notation

Front

What is orbital notation?

Back

Orbital notation is a way of representing the arrangement of electrons in an atom's orbitals using arrows to indicate the direction of electron spins.

Front

What does the d sublevel represent in electron configuration?

Back

The d sublevel represents a set of five orbitals that can hold a maximum of 10 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 s sublevel?

Back

The s sublevel can hold a maximum of 2 electrons.

Front

What is the significance of 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 each orbital can hold a maximum of two electrons with opposite spins.

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.

What is the electron configuration for oxygen (O)?

Back

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

Front

What is the electron configuration for bromine (Br)?

Back

The electron configuration for bromine is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵.

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

Back

The f sublevel can hold a maximum of 14 electrons.

What does the term 'valence electrons' refer to?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.
