Which of the following goes against (n+ l) rule, if levels filled up to
(1) 3p-orbitals, the next electron enters into 4s-orbital
(2) 4s-orbitals, the next electron enters into 3d-orbital
(3) 4s- & 3d-orbitals, the next electron enters into 4p-orbital
(4) 4s-orbitals, the next electron enters into 4p-orbital

No (4) goes against (n+l) rule because :
4s = (4+0) = 4.
3d = (3+2) = 5.
4p = (4+1) = 5.
Here, though 3d and 4p has equal (n+l) value, electron will enter 3d first because it has less n value.
Thank You !
