They have seven electrons in their outer shell they are in group seven on the periodic table.
a. carbon - 4 b. iodine - 12 c. calcium - 2 d. gallium - 3
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.
An iodine atom has 46 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding. In the case of iodine, the core electrons would include the 36 electrons found in the first four electron shells.
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.
