What is the maximum charge an ion is likely to have? These electrons are the ones most likely to be lost or gained to produce ions. ( Iodine has 7, and it won't have more unless it gains electrons from another atom.) How many valence electrons does an iodine atom have? Identify the number of protons and electrons in fluorine and iodine. That means that a neutral iodine atom will have a total of 53 electrons surrounding its nucleus. Anonymous. Answer.

This may seem a bit confusing when one looks at the periodic table, since chlorine is the seventh element in its row, but iodine is the seventeenth. All you have to do is place the first two dots on top, and then you alternately place one on each side until you run out of valence electrons. Fluorine also has 7 valence electrons, but cannot exceed an octet because it is in the second period. For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively. Chemistry.
