Electron Configuration & Orbital Notation

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What is orbital notation?

Back

A visual representation of the electron configuration of an atom, using arrows to represent electrons and boxes to represent orbitals.

Front

Which sublevel can hold a maximum of 2 electrons?

Back

The s sublevel.

Front

How many orbitals are in the p sublevel?

Back

3 orbitals.

Front

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

Back

10 electrons.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers; thus, an orbital can hold a maximum of 2 electrons with opposite spins.

Front

What is Hund's Rule?

Back

Electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

Front

What is the order of filling orbitals according to the Aufbau principle?

Back

Electrons fill orbitals starting from the lowest energy level to the highest.

Front

What does the term 'valence electrons' refer to?

Back

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

Front

What is the significance of the 3p orbital?

Back

It is a higher energy level than 2s and 2p orbitals, meaning it can hold electrons with more energy.
