A) inner-transition metal
B) alkaline earth metal
C) alkali metal
D) transition metal.
Correct Answer: B
Solution :
Electronic configuration of element Og (118) is \[[Rn]5{{f}^{14}}6{{d}^{10}}7{{s}^{2}}7{{p}^{6}}.\]Thus, next electron will go in 8s-orbital. Thus, element with Z = 120 will be an alkaline earth metal.
