The elements `Z = 117` and `120` have not yet have been discovered, In which family`//`group would you place these elements and also give the electronic configuration in each case. |
| Answer» The electronic configuration of Z=117 would be [Rn] `5f^(14)6d^(10)7s^(2)7p^(5)`. The element belongs to `17^(th)` group i.e., of halogen. Whereas the element with Z=120, the electronic configuration would be [Uuo]`8s^(2)` i.e., belongs to the `2^(nd)` group i.e., of alkaline earth metal. | |
