Question

use the drop - down menus to classify the elements as alkali metals, alkaline earth metals, or transition metals.
nickel (ni):
potassium
cadmium (
calcium (c
barium (ba)

Explanation:

Classify each element based on its position in the periodic table:

1. Nickel (Ni) is in group 10, a d-block element, so it is a transition metal.
2. Potassium (K) is in group 1, so it is an alkali metal.
3. Cadmium (Cd) is in group 12, a d-block element, so it is a transition metal.
4. Calcium (Ca) is in group 2, so it is an alkaline earth metal.
5. Barium (Ba) is in group 2, so it is an alkaline earth metal.

Answer:

• Nickel (Ni): transition metal
• Potassium (K): alkali metal
• Cadmium (Cd): transition metal
• Calcium (Ca): alkaline earth metal
• Barium (Ba): alkaline earth metal
