Answer:
6 orbitals
Step-by-step explanation:
An atom of mercury will have 6 - orbitals because it can be found on the 6-period in the periodic table of elements.
Orbitals or shells are energy levels in which electrons are placed within an atom.
Let us write the shell notation of the element:
Hg has 80 electrons:
K L M N O P
2 8 18 32 18 2
So, we have six orbitals
