Cadmium Ionic Charge and Properties

The video tutorial explains the ionic charge of cadmium (Cd) and its behavior on the periodic table. Cadmium is a transition metal that consistently forms a 2+ ion by losing two electrons. This process is contrasted with other transition metals that can have multiple ionic charges. The video also describes how cadmium interacts with chlorine to form cadmium chloride, emphasizing the charge balance. Additionally, the distinction between ionic charge and oxidation number is highlighted.

What is the state of cadmium on the periodic table?

• Negatively charged

• Variable charge

• Positively charged

• Neutral

How does cadmium's ionic charge compare to other transition metals?

• It forms a 3+ charge.
