The element, with atomic number 118, will be

Options

  1. Aalkali
  2. Bnoble gas
  3. Clanthanide
  4. Dtransition element

Correct answer

B. noble gas

Step-by-step solution

Electronic configuration of element with atomic number 118 will be [ Rn ] 5 f ¹⁴ 6 ~d ¹⁰7 ~s ² 7 p ⁶ . Since its elctronic configuration in the outer moot or bit (ns ² n p⁶ ) resemble with that of inert or noble gases, therefore it will be noble gas element.
