Given below are two statements :
Statement I : The electronegativity of group 14 elements from Si to Pb gradually decreases.
Statement II : Group 14 contains non-metallic, metallic, as well as metalloid elements.
In the light of the above statements, choose the most appropriate from the options given below :

We need to evaluate two statements about Group 14 elements.

Analysis of Statement I: "The electronegativity of Group 14 elements from Si to Pb gradually decreases."

This is FALSE. While there is a general decreasing trend in electronegativity going down the group, it is NOT a gradual or monotonic decrease. The electronegativity values (Pauling scale) are approximately: C (2.5), Si (1.8), Ge (2.0), Sn (1.8), Pb (1.9). Notice that germanium has a higher electronegativity than silicon, and lead has a higher electronegativity than tin. This irregularity is attributed to the poor shielding effect of d-electrons (for Ge) and f-electrons (for Pb), known as the d-block contraction and lanthanide contraction respectively.

Analysis of Statement II: "Group 14 contains non-metallic, metallic, as well as metalloid elements."

This is TRUE. Group 14 shows a clear transition from non-metal to metal:

- Carbon: Non-metal

- Silicon and Germanium: Metalloids (semi-metals with intermediate properties)

- Tin and Lead: Metals

This is a characteristic feature of p-block groups, where metallic character increases down the group.

The correct answer is Option (1): Statement I is false but Statement II is true.
