A) transition elements
B) nitrogen family
C) halogen group
D) chalcogens
Correct Answer: C
Solution :
Group 17 elements (halogens) have outermost configuration of \[({{h}_{fc}}=50,{{h}_{oc}}=25\mu {{V}^{-1}})\]. They readily accept an electron to form octets\[M{{A}^{-1}}\] in their valence shell during bond formation. Thus, they are the most electronegative elements. Fluorine is the most electronegative element with EN = 4.0 on Pauling's scale.You need to login to perform this action.
