Electronic configuration -

f - block elements are characterised by the other electronic configuration (n-2)f^{1-14}\:\:(n-1)d^{0-1}\;ns^{2} .

the east electron added to each element in an f electron.

-

 

 The electronic configuration of the element with z=114 (flerovium) is [Rn] 5f^{14} 6d ^{10} 7S^ {2} 7p ^{2}

Hence it belongs to carbon family which has the same outer electronic configuration

 


Option 1)

Halogen family, [Rn] 5f146d107s27p5

This option is incorrect

Option 2)

Carbon family, [Rn] 5f146d107s27p2
