42. The element, with atomic number 118 , will be
[1996]
(a) alkali
(b) noble gas
(c) lanthanide
(d) transition element
Show Answer
Answer:
Correct Answer: 42.(b)
Solution:
(b) Electronic configuration of element with atomic number 118 will be $[Rn] 5 f^{14} 6 d^{10} 7 s^{2} 7 p^{6}$. Since its elctronic configuration in the outer most orbit $(n s^{2} n p^{6})$ resemble with that of inert or noble gases, therefore it will be noble gas element.
