All About Electronic configuration of atoms

Electronic configuration, also known as electron structure, is the arrangement of energy levels of electrons around the nucleus. As far as finer quantum mechanical models are concerned, the K-Q shell is subdivided into a set of orbits (see orbits), each of which can be occupied by no more than a pair of electrons. The electron…
