The third principal energy level consists of s, p, and d atomic orbitals. Specifically, there are one 3s orbital, three 3p orbitals, and five 3d orbitals in the third principal energy level.
In Fe atoms, the 3d orbitals are partially filled. Iron (Fe) has an electron configuration of [Ar] 3d^6 4s^2, where the 3d orbitals contain 6 electrons.
Vanadium (V) contains 5 electrons in its 3d orbitals.
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
In the context of atomic orbitals, the 2d orbital does not exist. The electron orbitals in an atom are defined by three quantum numbers: principal quantum number (n), angular momentum quantum number (l), and magnetic quantum number (m). The angular momentum quantum number (l) can take values of 0 to (n-1), meaning the d orbitals start at l=2, corresponding to the 3d orbitals.

There are a total of 9 orbitals within the 3s, 3p, and 3d sublevels of the third energy level. The 3s sublevel has 1 orbital, the 3p sublevel has 3 orbitals, and the 3d sublevel has 5 orbitals.

Vanadium (V) contains 5 electrons in its 3d orbitals.
There are five different d orbitals within the 3d sublevel: 3dz², 3dxz, 3dyz, 3dx²-y², and 3dxy.
After the 4s orbital, the next orbital in order of increasing energy is the 3d orbital. The 3d orbital has a more complex shape compared to the s and p orbitals and can hold up to 10 electrons.
