Question 32

Given below are two statements:
Statement (I): Both metal and non-metal exist in p and d-block elements.
Statement (II): Non-metals have higher ionisation enthalpy and higher electronegativity than the metals.
In the light of the above statements, choose the most appropriate answer from the options given below:

Statement I: Both metals and non-metals exist in p-block and d-block elements.

Analysis: p-block contains both metals (e.g., Al, Ga, Sn, Pb) and non-metals (e.g., C, N, O, F, Cl). However, d-block elements are all metals — there are no non-metals in the d-block.

Statement I is false.

Statement II: Non-metals have higher ionisation enthalpy and higher electronegativity than the metals.

Analysis: This is generally true. Non-metals tend to have higher ionization enthalpies and higher electronegativities compared to metals, as they hold onto their electrons more tightly.

Statement II is true.

The answer is Option B: Statement I is false but Statement II is true.
