Answer 2

Explanation:

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. In terms of a more refined, quantum-mechanical model, the K–Q shells are subdivided into a set of orbitals (see orbital), each of which can be occupied by no more than a pair of electrons. The table below lists the number of orbitals available in each of the first four shells.The electronic configuration of an atom in the shell atomic model may be expressed by indicating the number of electrons in each shell beginning with the first. For example, sodium (atomic number 11) has its 11 electrons distributed in the first three shells as follows: the K and L shells are completely filled, with 2 and 8 electrons respectively, while the M shell is only partially filled with one electron.The electronic configuration of an atom in the shell atomic model may be expressed by indicating the number of electrons in each shell beginning with the first.
