Question

Among the following most electropositive element is

Easy

A

Al
B

Ga
C

In
D

Tl

Solution

In III_A group the least electronegative element is "Al" and highest electronegative element is ''B''.
The electro negativity order is,
B > Tl > In > Ga > Al
$Electro\,negativity \propto \,\frac{1}{{Electro\,positivity}}$
$\therefore$
Electro positivity order is,
B < Tl < In < Ga < Al
B — Non metal
Al — metal
Ga,In — Metalloid
Tl — metal
