Which of the following statements is correct with reference to the representative elements?

Correct option is B

The correct answer is (B) They consist of both s- and p-block elements.

Explanation:

• The representative elements are those elements that belong to the s-block and p-block of the periodic table. These elements include metals, nonmetals, and metalloids.
• The representative elements are typically found in groups 1, 2, and 13 to 18 of the periodic table, which include elements like alkali metals, alkaline earth metals, and halogens.

Information Booster:

• s-block elements are those found in Groups 1 and 2, which are metals like sodium and calcium.
• p-block elements are those found in Groups 13 to 18, which include nonmetals like oxygen, and metals like aluminum.

Additional Information:

• (A) They contain only metals: This is incorrect. Representative elements include both metals (e.g., sodium) and nonmetals (e.g., oxygen).
• (C) They only include p-block elements: This is incorrect. Representative elements also include s-block elements, not just p-block elements.
• (D) They are also called Transuranium elements: This is incorrect. Transuranium elements are elements with atomic numbers greater than uranium (atomic number 92), which are not representative elements.
