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):

Answer 1

Answer:

Nickel, Cadmium,are Transition elements,

Calcium, Barium are Alkaline earth elements

Potassium is Alki element

Explanation:

Ptassium belong to IA group n-1 configuration

Calcium and Barium belong to IIA group n-1 configuration

Nickel and Cadmium are transition, because their n-2 shell incompletly filled

Answer 2

The elements are categorized below -

Potassium (K): Alkali metal

Barium (Ba), Calcium (Ca): Alkali earth metals

Cadmium (Cd), Nickel (Ni): Transition metals

• Metals are the category of elements that have characteristic properties like lustrous or shiny appearance, good conductors of heat, and electricity. The strength and durability of metals are responsible for the numerous applications of metals.
• Alkali metals are different from alkaline earth metals in softness, comparatively lower melting point, strong basic nature, etc. in the former.
• Transitio nal metals are the metals that exist between s-block elements and p-block elements. Their properties vary between the nature of these two types and hence they are named transition metals.
• Alkali metals have one electron in their outermost shell (s), and alkaline earth metals have two electrons in their outermost shell (s). Transition metals have electrons in the d shell as the outermost shell.
