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 option given below:
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 option given below:
- (A)Both Statement I and Statement II are false
- (B)Statement I is false but Statement II is true✓ Correct
- (C)Statement I is true but Statement II is false
- (D)Both Statement I and Statement II are true
Answer: (B)
Solution
The p-block contains both metals (Al, Ga, In, Sn, Pb, Bi) and non-metals (C, N, O, halogens), but the d-block consists entirely of metals — no d-block element is a non-metal. So Statement I, which claims both metals and non-metals occur in both blocks, is false. Non-metals do have higher ionisation enthalpy and higher electronegativity than metals, since they hold their valence electrons more tightly and have a stronger tendency to gain electrons — Statement II is true.
