S-Sulphur atomic number is 16. n atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. The electron configuration is the standard notation used to describe the electronic structure of an atom. Such behavior is dependent on the number of electrons an atom has that are spin paired. In the case of equal n + ℓ values, the subshell with a lower n value is filled first. Each element has a unique atomic structure that is influenced by its electronic configuration, which is the distribution of electrons across different orbitals of an atom. 1-12 Mg. 2-13 Al. The electron configuration of an element describes how electrons are distributed in its atomic orbitals. However, the electrons in one subshell do have exactly the same level of energy, with later subshells having more energy per electron than earlier ones. The Aufbau principle. So, it has a total of 16 electrons. E.g. ), Sorting the table by chemical group shows additional patterns, especially with respect to the last two outermost shells. In this model the electron cloud of a multi-electron atom may be seen as being built up (in approximation) in an electron configuration that is a product of simpler hydrogen-like atomic orbitals.
