MCQ
Given below are two statements :

Statement $I$ : The electronegativity of group $14$ elements from $\mathrm{Si}$ to $\mathrm{Pb}$ 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 :

  •  Statement $I$ is false but Statement $II$ is true
  • B
     Statement $I$ is true but Statement $II$ is false
  • C
     Both Statement $I$ and Statement $II$ are true
  • D
     Both Statement $I$ and Statement $II$ are false

Answer

Correct option: A.
 Statement $I$ is false but Statement $II$ is true
a
$Gr-14$   $EN$

$C$               $2.5$

$Si$              $1.8$

$Ge$            $1.8$

$Sn$            $1.8$

$Pb$            $1.9$

The electronegativity values for elements from $\mathrm{Si}$ to $\mathrm{Pb}$ are almost same. So Statement $\mathrm{I}$ is false.
