Question

2d is impossible why?​

Answer 1

1 D , 2D , 3D is possible

but drawing 4D is impossible

Answer 2

Answer:

In the ground state for each energy level: In the 2nd energy level, electrons are located only in the s and p sublevels, so there are no d orbitals. ... In the 3rd energy level, electrons occupy only the s, p, and d sublevels, so there is no f sublevel. That is why 2d and 3d orbitals are not possible.
