The key term that corresponds to the definition “a method of writing an electron configuration in which core electrons are represented by a noble gas symbol in brackets followed by the valence electrons, for example, [ Ne ] 3 s 2 ” is to be stated. Concept introduction: The electrons of an element are arranged in its atomic shell systematically. The systemic arrangement of an electron in an atom is known as electronic configuration. The order of filling of electrons is provided by the Aufbau. According to the Aufbau, the electron in an atom are filled in the increasing order of energy of sublevels.
