The third shell also has 8 electrons, but things get more complicated after than because the subshells spread out enough that there is overlap between them. The second shell, associated with principal quantum number n=2, can have a maximum of 8 electrons and corresponds to the second period of the periodic table. The number of electrons in a given shell can be predicted from the quantum numbers associated with that shell along with the Pauli exclusion principle. So hydrogen and helium complete the first period. In the periodic table, the elements are placed in "periods" and arranged left to right in the order of filling of electrons in the outer shell. The first shell (n=1) can have only 2 electrons, so that shell is filled in helium, the first noble gas. These are useful in the noble gas configuration which is composed of the elemental symbol of the last noble gas before it succeeded by its remaining electrons. These gases are helium, neon, argon, krypton, xenon, and radon. Weve got the study and writing resources you need for your assignments. In the periodic table of elements, the last column provides an important group of elements known as the noble gases.
