Periodic Table of Elements Element Iodine - I. When I was a child, I used spend a couple of weeks each summer high in the Italian Alps in an idyllic little village called Cogne that nestles quietly between high ice-clad peaks. The number of electron shells or energy levels are the same number as the period they are in, for example, all elements in the second period have 2 energy levels or electron shells.
