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 metalloi

Question

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:

Canvas Classes · Accepted Answer

Statement I: Electronegativity of Group 14 from Si to Pb does NOT decrease gradually. There are anomalies due to d-orbital contraction (Ge has slightly higher EN than Si). Statement I is false. ✗

Statement II: Group 14 contains:
- Non-metals: C (diamond, graphite, fullerenes)
- Metalloids: Si, Ge
- Metals: Sn, Pb

Statement II is true. ✓

Answer: Option (1) — Statement I is false but Statement II is true
