What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating how electrons are arranged around the nucleus.

Front

What is the maximum number of electrons that can occupy a single orbital?

Back

2 electrons, due to the Pauli exclusion principle.

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 Pauli exclusion principle?

Back

No two electrons in an atom can have the same set of four quantum numbers.

Front

What is the Aufbau principle?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is the electron configuration for Lithium?

Back

1s² 2s¹.

Front

What is the electron configuration for Magnesium?

Back

1s² 2s² 2p⁶ 3s².

Front

How many electrons are in a Neon atom?

Back

10 electrons, with the configuration 1s² 2s² 2p⁶.

Front

What is the significance of the 's', 'p', 'd', and 'f' in electron configurations?

Back

They represent different types of atomic orbitals with distinct shapes and energy levels.

Front

What is the maximum number of electrons in the p subshell?

Back

6 electrons, as there are three p orbitals.
