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 's' sublevel represent in electron configurations?

Back

The 's' sublevel is one of the types of atomic orbitals that can hold a maximum of 2 electrons.

Front

How many electrons can the 'p' sublevel hold?

Back

The 'p' sublevel can hold a maximum of 6 electrons.

Front

What is the maximum number of electrons in the first energy level?

Back

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

Front

Which orbital has the highest energy: 2p, 2s, 3p, or 1s?

Back

3p has the highest energy among the given orbitals.

Front

What is the Aufbau principle?

Back

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

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 an orbital diagram?

Back

An orbital diagram is a visual representation of the electron configuration of an atom, showing the distribution of electrons in orbitals.

Front

What is the significance of the quantum numbers?

Back

Quantum numbers describe the properties of atomic orbitals and the electrons in those orbitals, including their energy, shape, and orientation.
