They have seven electrons in their outer shell they are in group seven on the periodic table.
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.
Bromine borrows 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.
only one electron can be lost from the sodium atom.
