Here’s the classification of each element in Column A with the appropriate category from Column B:
- Silver (Ag): c. Transition Metal
- Barium (Ba): a. Alkaline Earth Metal
- Iodine (I): b. Halogen
- Argon (Ar): d. Noble Gas
- Potassium (K): e. Alkali Metal
So the completed pairs will look like this:
- Silver (Ag): Transition Metal
- Barium (Ba): Alkaline Earth Metal
- Iodine (I): Halogen
- Argon (Ar): Noble Gas
- Potassium (K): Alkali Metal
