How to write Orbital Diagram of Mercury?
Mercury (Hg) packs 80 electrons uniquely. Unlike its group members, it fills its inner 5d subshell completely. Its configuration is [Xe] 4f¹⁴ 5d¹⁰ 6s² -. It fills electrons in inner shells before adding to the outer 6s subshell (6s²). This complete inner shell setup is believed to influence Mercury’s surprising liquid state at room temperature.
