Answer:

Well for mercury, #Z=80...#

Explanation:

And so for #Hg# we got 80 electrons to distribute according to the Aufbau scheme....

#underbrace(1s^(2)2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 5s^2 5p^6 4f^14 5d^10 6s^2)_"configuration of mercury metal"#

And so for #Hg^(2+)# we got 78 electrons to distribute ….....

#underbrace({1s^(2)2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^10 5s^2 5p^6 4f^14 5d^10}^(2+))_"configuration of mercuric ion"#

Are there the right number of electrons? All care taken, but no responsibility admitted...
