Practice: Which electron configuration represents a violation of Hund’s Rule?
The electron configuration of an element is the distribution of its electrons within atomic orbitals.
The Electron Configuration
Concept #1: Electron Orbital Diagrams
Example #1: Properly fill in the orbitals of an atom that possesses 8 electrons within its d set of orbitals.
Concept #2: Ground State Electron Configurations
Concept #3: Auf Bau Principle
Example #2: Write the ground state electron configuration for the following element: Fluorine (Z = 9)
Practice: Which electron configuration represents a violation of the Auf Bau Principle?
Practice: Identify the element with the given electron orbital diagram.
Practice: Write the electron configuration and electron orbital diagram for the following element:
Sulfur (Z = 16)
Practice: Write the ground state electron configuration for the following element:
Magnesium (Z = 12)
Concept #4: Unpaired vs Paired Electrons
Example #3: Determine the number of unpaired electrons in vanadium.
Practice: Which of the following atoms has the most unpaired electrons?
