Interpretation: The reason for electrons in
Concept introduction: This can be explained by Hund’s rule of maximum multiplicity.
According to Hund’s rule,
“Before the orbital is doubly occupied, every orbital in the sub level is singly occupied”.
Answer to Problem 66A
Electrons gets fill in two different
Explanation of Solution
Many unpaired electrons are present in atoms which are at the ground state. Since electrons are tiny bar magnet if two electrons come in contact they would show the same behavior as two magnets do. The electrons first try to get as far away from each other as possible before they have to pair up due to repulsion between them. Hence electron will not pair with another electron in a half-filled as long as vacant orbital of similar energy is available.
As obvious from orbital diagram that electrons first getting filled up in different
