The valence electronic configuration of an atom is 6s^2 If d-orbital of the penultimate shell contains two unpaired electrons, calculate the atomic number |
| Answer» SOLUTION :Sincethe valence electronic configuration of the atom is `6s^2` and cl-orbital of the penultinute shell CONTAINS TWO UNPAIRED electrons, the electromc configuration is `[Xe]6s^24f^(14)5d^2`Therefore, the atomic NUMBER of the elen1ent is 72. | |
