Academic Partner. Electronic configuration, also called electronic structure, the arrangement of electrons in energy levels around an atomic nucleus.According to the older shell atomic model, electrons occupy several levels from the first shell nearest the nucleus, K, through the seventh shell, Q, farthest from the nucleus. Iron's atomic number is 26. The atomic number of iron is 26. two. Electron configuration was first conceived under the Bohr model of the atom, and it is still common to speak of shells and subshells despite the advances in understanding of the quantum-mechanical nature of electrons. The electron configuration of an atom of any element is the of electrons per sublevel of the energy levels of an atom in its ground state. Electron shells consist of sub-shells denoted s, p, d and f. When adding electrons around a nucleus, the electrons are always placed in the shell with the lowest number first, then the second lowest one, and so on. The value of n, the principal quantum number, for the valence shell is the period of the element. The atomic number of chlorine is 17. For each electron shell atom diagram, the element symbol is listed in the nucleus. GEORGIANNA. Why is that? This means that there are 3 electrons in the 3 rd shell and 2 electrons in the 4 th, or valence shell. The alkali metals and alkaline earth metals have one and two valence electrons (electrons in the outer shell), respectively; because of this, they lose electrons to form bonds easily and so are very reactive. The arrangement of electrons in shells around the nucleus of an atom is referred to as the electron configuration. The distribution of electrons in an atom is referred to as electron configuration. It's easier to understand electron configuration and valence if you can actually see the electrons surrounding atoms. For that, we have electron shell diagrams..
