Question

of mercury.. [Xe] 6s2 5d10?
is this correct, if not what have i not considered?

Answer 1

You left out the "f" orbitals.

Follow the increasing atomic numbers as you move across the periodic table, and you'll see that you have to go through the lanthanides before you go to the "d" block.

mercury is [Xe] 6s2 4f14 5d10
