The atomic number of the undiscovered element is 168
Element 118 will have just filled its 7p orbitals. therefore the predicted element to fill completely up to its 8 p orbital would have to filled a whole set of s, p, d, f and g orbitals
That's another 2 + 6 + 10 +14 + 18 = 50 electrons
To determine the total number of quantum numbers we have to find
Nml × Nms
we have Nml × Nms = ( 2 + 1 ) × 2
8s + 8P + 7d + 6f + 5g = 2 + 6 + 10 + 14 + 18 = 50
The element right below should be
Z = 118 + 50
= 168
Hence the atomic number of the undiscovered element is 168

Answer: The ocean plays a key role in this vital cycle of water. The ocean holds 97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation. ... Water evaporates from the surface of the ocean, mostly in warm, cloud-free subtropical seas.
