Verified step by step guidance1
Identify the atomic number of cadmium (Cd), which is 48. This means a neutral cadmium atom has 48 electrons.
Determine the charge of the cadmium ion. The problem does not specify, but common cadmium ions are Cd²⁺.
Understand that a Cd²⁺ ion means the cadmium atom has lost 2 electrons.
Calculate the number of electrons in the Cd²⁺ ion by subtracting 2 from the original 48 electrons: 48 - 2.
Conclude that the Cd²⁺ ion possesses 46 electrons.
