2d Only s and p in the 2 level
2d is invalid. Only s and p orbitals in 2nd energy level
3d orbitals do exist and 2d orbitals dont exist because of the pauli exclusion principle which says only 6 electrons can exist in the 2nd shell, and you need at least 7 to get a d subshell

Yes it is possible. When the object is kept in between F and 2F, then an enlarged real but inverted image is got beyond 2F on the other side of the lens.
2f + 8 = 103 2f = 95 f = 47.5

The 'd' orbitals of Cadmium are full filled therefore transition of electrons is not possible within 'd' orbitals so compound is colorless.
The 2d sub energy level does not exist. The first shell to contain a d sub-shell is the third shell: the 3d sub-shell contains a maximum of 10 electrons, with two electrons in each of five different d orbitals.
