The correct option with respect to the Pauling electronegativity values of the element is: (1) Ga < Ge (2) Si < Al (3) Te > Se (4) P > S

1. Ga < Ge
2. Si < Al
3. Te > Se
4. P > S

Correct answer: Ga < Ge

Solution

Gallium has a lower electronegativity than germanium due to its position in the periodic table, where gallium is located in the same group as aluminum but has additional electron shielding that reduces its effective nuclear charge on valence electrons.
