Electron configuration

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level and sublevel.

Front

How many electrons can the d sublevel hold?

Back

10 electrons.

Front

What is the maximum number of electrons that an s orbital can have?

Back

2 electrons.

Front

How many electrons can the p sublevel hold?

Back

6 electrons.

Front

What is the maximum number of electrons that an f orbital can have?

Back

14 electrons.

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.

What is the significance of the principal quantum number (n)?

Back

The principal quantum number (n) indicates the main energy level of an electron in an atom.
