Question
Chemistry Question on GROUP 14 ELEMENTS
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:
Both Statement I and Statement II are false
Both Statement I and Statement II are true
Statement I is true but Statement II is false
Statement I is false but Statement II is true
Statement I is false but Statement II is true
Solution
The electronegativity values for Group 14 elements from Si to Pb are almost the same, with values approximately as follows:
Therefore, Statement I is false as there is no gradual decrease in electronegativity from Si to Pb.- Statement II is true because Group 14 does indeed contain non-metallic (C), metalloid (Si, Ge), and metallic (Sn, Pb) elements.
So, the correct answer is : Statement I is false but Statement II is true
