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

zero - after the 4s orbitals are filled at Calcium, the 3d orbitals start to fill - not until Gallium do the 4p orbitals start to fill.

The number of atoms in 1/2 gram of the chemical element copper is 4.7384X10^21. Copper has the atomic number 29 and its symbol is Cu.
The 4d orbital would be the same shape as the 3d orbital, but just a larger size. Also it would have more nodes than he 3d orbital.
