Hund's rule states that when a sublevel contains several orbitals of equal energy, electron(s) must be placed in each orbital before electrons are <u>paired.</u>
<u />
According to Hund's rule, each orbital within a sublevel is always singly occupied before it becomes double occupied. Every electron in solely filled orbitals possesses the same spin.
Only when every orbital in a sublevel has one electron would electrons pair up inside an orbital. They are all the same spin whenever a single electron is present in many orbitals within the same sublevel.
Therefore, Hund's rule states that when a sublevel contains several orbitals of equal energy, electron must be placed in each orbital before electrons are <u>paired.</u>
