Hund's Rule, Pauli Exclusion Principle & Orbitals Diagrams

An electron occupies the lowest energy orbital that can receive it.

• Hund’s rule
• Pauli exclusion principle
• Bohr model of the atom
• Aufbau principle

All orbitals of equal energy are occupied by one electron before any single orbital is occupied by a second electron.

• Pauli Exclusion Principle

Which element is pictured?

What is incorrect about this orbital diagram?

• Both arrows in the 2p orbital (box) should be pointing up

• There is nothing incorrect with this diagram

• In the 2p orbital (box) there should only be 1 electron in the first 2p orbital and one in the 2nd 2p orbital

• All the arrows should be pointing up first before you write them pointing down in the same orbital

In 1s² , the 1 indicates

• Energy sublevel

• Main energy level

• Number of orbitals (boxes) in the sublevel

• Number of electrons

Electrons occupy orbitals of lowest energy first is part of what electron configuration rule?

• Hund’s Rule
• Aufbau Principle
  
• Pauli Exclusion Principle
