Each row on the periodic table represents:

Back

an energy level

Front

What does Hund's rule state?

Back

An orbital can contain two electrons only if all other orbitals in that sublevel contain at least one electron.

Front

Why do electrons enter the 4s orbital before entering the 3d orbital?

Back

because the 4s orbital is at a lower energy level

Front

What does the sign represent with respect to electrons?

Back

opposite spin of two electrons

Front

According to the Pauli exclusion principle, when can two electrons occupy the same orbital?

Back

only if they have opposite spins
