The element, with atomic number 118, will be

The element, with atomic number 118,118, 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\mathrmf146d107s27\mathrmp6.[\mathrm{Rn}] 5 \mathrmf^{14} 6 \mathrm{ d}^{10}7 \mathrm{ s}^{2} 7 \mathrmp^{6}. Since its elctronic configuration in the outer moot or bit (ns ^{2} n p^{6})resemblewiththatofinertornoblegases,thereforeitwillbenoblegaselement.) resemble with that of inert or noble gases, therefore it will be noble gas element.
