The numbers are staggering; the Napoleonic census of the canton of Valais in 1800 found 4000 cretins in a population of 70,000 - well over 50% would have had goiter. What is the wavelength (in nm) of a photon if the energy is 5.94 1 0 19 J? One electron must be paired with another in one of the 2p orbitals, which gives us two unpaired electrons and a 1s22s22p4 electron configuration. We already know that the p-subshell has three orbitals. We will use neon for the noble gas configuration because it is in period 2. That was UCL chemist Andrea Sella telling the tale of iodine, element number 53. The elements that have 5, 6, or 7 electrons in the last shell receive the electrons in the last shell during bond formation. Values are given for typical oxidation number and coordination. Therefore, an iodine atom will have two electrons in the first shell, eight in the 2nd orbit, and eighteen electrons in the 3rd shell. A percentile rank for the political stability of the country with the largest reserves, derived from World Bank governance indicators. This means that the chemistry of an atom depends mostly on the electrons in its outermost shell (with the greatest "n" value), which are called the valence electrons.
