Electron configuration flashcard

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 the maximum number of electrons that can occupy the s sublevel?

Back

2 electrons.

Front

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

Back

6 electrons.

Front

What is the electron configuration for Magnesium (Mg)?

How many total electrons are in a neutral atom of Copper (Cu)?

Back

29 electrons.

Front

What is the significance of the Aufbau principle in electron configuration?

Back

It states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What does Hund's rule state about electron configuration?

Back

Electrons will fill degenerate orbitals 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.
