Question

Why are the halogens in group 7?

Answer 1

1. Halogens are present in group 7 of the periodic table and are electronegative in nature.
2. Halogens are highly reactive and toxic in nature.
3. The group 7 elements are Fluorine, Chlorine, Bromine, Iodine, and Astatine.
4. The elements of this group contain 7 electrons in their outermost shell so they require only one electron to complete their octet.
5. Therefore they form anions by accepting the electrons, also called halides.
6. In their elemental form, they are present in diatomic molecules.
7. They are nonpolar in nature.
