Most Electron Configuration Exceptions are the result of elements drive to obtain half filled or totally filled d orbitals

Electron Configuration Exceptions

Concept #1: Electron Orbital Stability

Concept #2: Exceptions to Electron Configurations

Concept #3: Half-filled Orbitals

Concept #4: Completely-filled Orbitals

Example #1: Based on the exceptions, provide the condensed electron configuration for the silver atom.

Practice: Illustrate the exception to the electron configuration of molybdenum.

Practice: Which of the following is the correct electron configuration of gold? 

Practice: A comparison of the electron configurations of palladium (Pd) and silver (Ag) indicates that:
