(a) Interpretation: The given electronic configuration belongs to which neutral atom needs to be predicted. Whether it is for ground state or excited state needs to be identified. Concept introduction: According to Aufbau principle electrons are filled first in lower energy orbitals followed by higher energy orbitals. Hund’s rule states that while filling electrons in degenerate orbitals there will be single occupancy first and then only pairing can take place.
