What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

What is an orbital diagram?

Back

An orbital diagram is a visual representation of the arrangement of electrons in an atom's orbitals, using arrows to represent electrons.

What is the noble gas configuration for an element?

Back

The noble gas configuration is a shorthand notation that uses the electron configuration of the nearest noble gas to simplify the representation of an element's electron configuration.

Front

What is the difference between electron configuration and shorthand configuration?

Back

Electron configuration lists all the electrons in an atom, while shorthand configuration uses the nearest noble gas to represent the inner electrons.

What is the Aufbau principle?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.
