For
shortcuts to
the pages of this section, see Halogens.
The halogens are all in group 7 on the right of
the periodic
table.
They are Fluorine, Chlorine, Bromine and
Iodine.
They are all diatomic covalently bonded
molecules.
Diatomic means that each molecule contains two atoms.
The formulae are F2, Cl2, Br2, I2, (see structure of
chlorine).
All
of the halogens
will either
1) gain one electron from a metal to form an ionic bond
or
2) share one electron with a
non-metal to form a covalent bond
(see structure of chlorine or
hydrogen
chloride).
