In comparison to other groups, Group 17 has the highest electronegativity. A further explanation is below.
- The different components such as fluorine, chlorine, bromine, iodide, as well as actinides, are found throughout the periodic tables' Group number 17 elements. These would be referred to together as HALOGENS.
- Because these components frequently combine or interact with alkali metals as well as alkaline earth materials that can generate halide salts, this same name "halogen" implies "salt-former."
Thus the response above i.e., option (3) is right.
