Classification Of Elements And Periodicity In Properties Question 7
Question 7 - 2024 (29 Jan Shift 1)
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 :
(1) Statement I is false but Statement II is true
(2) Statement I is true but Statement II is false
(3) Both Statement I and Statement II are true
(4) Both Statement I and Statement II are false

Answer (1)
Solution
| Gr-14 | EN |
|---|---|
| $C$ | $2.5$ |
| $Si$ | $1.8$ |
| $Ge$ | $1.8$ |
| $Sn$ | $1.8$ |
| $Pb$ | $1.9$ |
The electronegativity values for elements from $Si$ to $Pb$ are almost same. So Statement $I$ is false.
