• A. transition element
• B. alkali
• C. alkaline earth metal
• D. noble gas.

Answer 1

Answer: (D)

noble gas.

Answer 2

Electronic configuration of element witn atomic number 118 will be $[ Rn ] 5 f^{4} 6 s^{2} 6 p^{6} .$ Since its electronic configuration in the outermost orbit $\left(n s^{2} n p^{6}\right)$ resembles with that of inert or noble gases, therefore it will be a noble gas element.
