Iodine is one of seven elements that usually form as diatomic molecules. These other "diatomics" are O_2, H_2, F_2, Br_2, N_2, and Cl_2. They typically bond to themselves.

Iodine has seven valence electrons. Using valence shell electron pair repulsion (VSEPR) theory, we can predict the Lewis dot structure for I_2. We see there are fourteen electrons, and we can make a covalent bond, leaving three lone pairs on each atom. The bond replaces two electrons, so the number of electrons shared is two.
