Back

The maximum number of electrons that can occupy the 3d sublevel is 10.

Front

What is the significance of the Aufbau Principle in electron configuration?

Back

The Aufbau Principle states that electrons fill atomic orbitals in order of increasing energy levels.

Front

How do you determine the number of valence electrons for an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.
