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: [Rn] 5f14 6d10 7s2 7p6
Since the outer shell has a complete octet (7s2 7p6), it would be a noble gas element.
