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 does the notation '1s²' represent?

Back

It indicates that there are 2 electrons in the 1s orbital.

Front

How many total electrons can the 2p sublevel hold?

Back

The 2p sublevel can hold a maximum of 6 electrons.

Front

What are valence electrons?

Back

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

Front

What is the noble gas shorthand for writing electron configurations?

Back

A method that uses the electron configuration of the nearest noble gas to simplify the representation of an atom's electron configuration.
