Electron Configuration

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 does the Aufbau Principle state?

Back

Electrons occupy orbitals of lowest energy first before filling higher energy orbitals.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in the same orbital can have the same spin.

Front

What is Hund's Rule?

Back

Single electrons with the same spin must occupy each energy orbital before additional electrons with opposite spins can occupy the same orbitals.

Front

How many electrons are in the configuration 1s²2s²2p⁶?

Back

10 electrons.

Front

What atom has the electron configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰?

Back

Zinc.

Front

What are anions?

Back

Negatively charged ions that form when nonmetals gain electrons.

Front

What are cations?

Back

Positively charged ions that form when metals lose electrons.

What is the maximum number of electrons in an s orbital?

Back

2 electrons.

Front

What is the maximum number of electrons in a p orbital?

Back

6 electrons.
