Halogens[]

Fluorine

Fluorine

Halogens are elements whose neutral atom is one electron short of a filled shell. This makes them nonmetals which readily form simple anions and which are negatively charged in polar covalent bonds. When electrons are removed from an atom, leaving a positive ion, we say the atom was oxidized. Therefore, halogens are oxidizing agents - very much so in the cases of Cl and F which are strong enough to oxidize xenon.

They are often found as salts, combined with alkali metals (Group 1)

Astatine (At) and Tennessine (Ts) are both technically halogens, although they lack the strong electronegativity that dominates the chemistry of lighter halogens. Both are more or less metals, like other post-transition metals such as Sn, Pb, or Bi.
