Verified step by step guidance1
Identify the element: Cadmium (Cd) is a transition metal with an atomic number of 48.
Determine the electron configuration of a neutral cadmium atom: The electron configuration is [Kr] 4d^10 5s^2.
Understand the ionization: Cd^2+ means cadmium has lost two electrons.
Remove the electrons from the outermost shell: The two electrons are removed from the 5s orbital, resulting in the electron configuration [Kr] 4d^10.
Draw the Lewis Dot symbol: Since the 5s electrons are removed, the Lewis Dot structure for Cd^2+ will not have any dots around the symbol for cadmium, and it should be enclosed in brackets with a 2+ charge indicated.
