Vedclass · Answer

(D) For group $13$ elements,electronegativity $(EN)$ decreases from $B$ to $Al$ due to the increase in atomic size. From $Al$ to $Tl$,the electronegativity increases gradually due to the poor shielding effect of $d$ and $f$ orbitals,which increases the effective nuclear charge. The values of $EN$ (on the Pauling scale) are: $B (2.0)$,$Al (1.5)$,$Ga (1.6)$,$In (1.7)$,and $Tl (1.8)$. Thus,the correct variation shows a decrease from $B$ to $Al$ followed by an increase from $Al$ to $Tl$.

Which one of the following correctly represents the variation of electronegativity $(EN)$ with atomic number $(Z)$ of group $13$ elements?
