Answer

Brief Explanations:

Classify elements based on their groups in the periodic table. Alkali metals are Group 1, alkaline earth metals Group 2, and transition metals are in the d-block.
Nickel (Ni) is in the d-block, potassium (K) Group 1, cadmium (Cd) d-block, calcium (Ca) Group 2, barium (Ba) Group 2.

Answer:

Nickel (Ni): Transition metals
Potassium (K): Alkali metals
Cadmium (Cd): Transition metals
Calcium (Ca): Alkaline earth metals
Barium (Ba): Alkaline earth metals
