Question

use the drop-down menus to classify the elements as alkali metals, alkaline earth metals, or transition metals

nickel (ni)
potassium (k)
cadmium (cd)
calcium (ca)
barium (ba)

Explanation:

Classify Nickel (Ni)

Using the Transition Metals knowledge point, Nickel (\(\text{Ni}\)) is located in Group 10 of the periodic table, which belongs to the d-block transition metals.

Classify Potassium (K)

Using the Alkali Metals knowledge point, Potassium (\(\text{K}\)) is located in Group 1 (alkali metals) of the periodic table.

Classify Cadmium (Cd)

Using the Transition Metals knowledge point, Cadmium (\(\text{Cd}\)) is located in Group 12 of the periodic table, which belongs to the d-block transition metals.

Classify Calcium (Ca) and Barium (Ba)

Using the Periodic Table Groups knowledge point, Calcium (\(\text{Ca}\)) and Barium (\(\text{Ba}\)) are located in Group 2 of the periodic table, which are the alkaline earth metals.

Answer:

Use the drop-down menus to classify the elements as alkali metals, alkaline earth metals, or transition metals:

Nickel (Ni): <blank>transition metals</blank>
Potassium (K): <blank>alkali metals</blank>
Cadmium (Cd): <blank>transition metals</blank>
Calcium (Ca): <blank>alkaline earth metals</blank>
Barium (Ba): <blank>alkaline earth metals</blank>
