Solution

The correct option is D Uuo ; Ununoctium ; noble gas
The roots of '1', '1' and '8' are 'un', 'un' and 'oct' respectively. Hence the name becomes Ununoctium and the symbol is 'Uuo'.
The electronic configuration of element having $Z = 118$ is: $[R n] 5 f^{14} 6 d^{10} 7 s^{2} 7 p^{6}$
Since the outer shell has a complete octet $(7 s^{2} 7 p^{6})$ , it would be a noble gas element.
