Answer:
The electronic configuration of iron is
Fe(Z=26) = 1s22s22p63s23p64s23d6
Iron (Fe) is a transition metal that fills atomic orbitals according to the Aufbau rule. Fe has an atomic number of 26, which means that the atoms have 26 protons in their nuclei and 26 electrons in their electron clouds if they are neutral. The electron configuration of Fe in its ground state is
1s22s22p63s23p64s23d6
