They have seven electrons in their outer shell they are in group seven on the Periodic Table.
Iodine, which is in Group 7 of the Periodic Table, has 7 electrons in its outer most shell xoxo
There are always 2 electrons in the inner-shell of iodine
Iodine has seven electrons in the outer ring and has a negative one charge.
There are 7 electrons in the outermost energy level of Iodine.

The atomic number of Iodine is 53, and so one atom of Iodine has 53 protons. In order for the charge to be balanced, each atom of Iodine must also have 53 electrons.
Iodine has 53 electrons. The atomic number equals the number of protons in an atom, and since iodine is neutrally charged, it also equals the number of electrons.
I am not positive what you mean by "core electrons" but: 57 (total) 7 (valence, outermost) 50 (non-valence, everyone but valence)

7 valence electrons in iodine
Iodine has 7 valance electrons
Iodine is a non metal element. There are 53 electrons in a single atom.
Iodine has 7 valence electrons like the other halogens.
Seven valence electrons in iodine.
The outer most electron shell of iodine atom contains 7 electrons.
The isotope iodine-122 has 53 protons and electrons and 69 neutrons.
As an iodine atom has 53 electrons, an iodide ion has 54 electrons.
