Explanation:
Electronic configuration is defined as the distribution of electrons in the energy levels around an atomic nucleus.
Atomic number helps in determining the electronic distribution of an atom.
We write electronic configuration according to Aufbau's principle in which shells are arranged in increasing energy levels.
Mercury (Hg) is a transition element and its atomic number is 80.
Electronic configuration of mercury is [tex][Xe]4f^{14}5d^{10}6s^{2}[/tex].
