Which of the following statements is NOT correct with reference to the p-block elements?

Correct option is A

The correct answer is (a) They are also called transition elements.

Explanation:

• Transition elements are not part of the p-block; they belong to the d-block (Groups 3 to 12).
• P-block elements are found in Groups 13 to 18 of the periodic table.
• Their valence shell electron configuration ranges from ns²np¹ to ns²np⁶, depending on the group.
• The p-block includes a wide variety of elements: metalloids, non-metals, halogens, and noble gases.
• Therefore, calling p-block elements "transition elements" is incorrect.

Information Booster:

• P-block elements show variable oxidation states, particularly in Groups 14 to 17.
• They display a wide range of properties due to their diverse nature (e.g., metals, non-metals, gases).
• Noble gases (Group 18) are chemically inert due to fully filled outer orbitals (ns²np⁶).
• Common elements include carbon, nitrogen, oxygen, fluorine, chlorine, silicon, and sulfur.

Additional Information:

• Option (b) is correct: p-block includes both non-metals (like O, N, F) and noble gases (He, Ne, Ar, etc.).
• Option (c) is correct: electronic configurations range from ns²np¹ (Group 13) to ns²np⁶ (Group 18).
• Option (d) is correct: p-block spans Groups 13 to 18 in the periodic table.
