Question

What are the elements of 17 groups? Explain the properties in the following points: Electronic configuration, electronegativity, oxidation state​

Answer 1

Answer:

All the Group 17 elements including fluorine, chlorine, bromine, iodine, and astatine are highly reactive nonmetals and are highly electronegative due to their highly effective nuclear charge. Halogens can gain an electron through reaction with other elements due to their high reactivity.
