Electron Configurations

Front

What is an electron configuration?

Back

An electron configuration is the distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level and sublevel.

Front

What are the four types of sublevels in electron configurations?

Back

The four types of sublevels are s, p, d, and f.

Front

How many electrons can the s sublevel hold?

Back

The s sublevel can hold a maximum of 2 electrons.

Front

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

Back

The d sublevel can hold a maximum of 10 electrons.

Front

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

Back

The f sublevel can hold a maximum of 14 electrons.

What is the significance of noble gas configurations?

Back

Noble gas configurations simplify electron configurations by using the electron arrangement of the nearest noble gas to represent inner shell electrons.

Back

The noble gas configuration for Neon is [He]2s²2p⁶.

Front

How do you determine the number of valence electrons in an atom?

Back

Valence electrons are determined by the electrons in the outermost energy level of an atom.
