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 :
Solution
<p>$$\begin{array}{ll}
\text { Gr-14 } & \text { EN } \\
\mathrm{C} & 2.5 \\
\mathrm{Si} & 1.8 \\
\mathrm{Ge} & 1.8 \\
\mathrm{Sn} & 1.8 \\
\mathrm{~Pb} & 1.9
\end{array}$$</p>
<p>The electronegativity values for elements from $\mathrm{Si}$ to $\mathrm{Pb}$ are almost same. So Statement $\mathrm{I}$ is false.</p>
