Electron Configuration

Front

What is electron configuration?

Back

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

Front

What is the electron configuration for an Oxygen atom?

Back

1s²2s²2p⁴.

Front

What is the significance of the Pauli Exclusion Principle in electron configuration?

Back

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

Front

What does the term 'valence electrons' refer to?

Back

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