Solution
The correct option is A 1
Electronegativity measures an atom's tendency to attract and form bonds with electrons. Group 17 or VIIA has most electron negative elements. This property exists due to the electronic configuration of atoms. Most atoms follow the octet rule (having the valence, or outer, shell comprise of 8 electrons). Because elements in the group have 7 electrons in the valence shell, are more energy-efficient in gaining an electron to create a complete valence shell of 8 electrons.
