What is the ground state shorthand notation for mercury (hg)?

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 .

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
