They have high melting and boiling points and are hard and brittle
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
