This group is also known as group 17. The halogens all have seven electrons in their outer shell and tend to have high electronegativities. Fluorine is the smallest member of the group, whilst the largest is astatine.

Occurrence, Preparation, and Properties of Halogens – Chemistry

WebHalogens range from solid (I 2) to liquid (Br 2) to gaseous (F 2 and Cl 2) at room temperature. As pure elements, they form diatomic molecules with atoms joined by non-polar covalent bonds. They all have very high electronegativity.
