The elements Z=117 and 120 have not yet ...

The elements Z=117 and 120 have not yet been discovered. In which family / group would you place these elements and also give the electronic configuration in each case.

Text Solution

Verified by Experts

We see from the periodic table that element with Z=117, would belong to the halogen family (group 17) and the electronic configuration would be. `[Rn] 4f^(14) 5d^(10) 7s^2 7p^5` . the element with Z=120, will be placed in group 2 (alkaline earth metals), and will have the electronic configuration `[Uuo]8s^2`.
