Question

2d and 3f orbitals are not possible​

Answer 1

Answer :

Answers from spammers u will get ☺︎︎

In the first shell, there is only the 1s orbital, as this shell can have a maximum of only 2 electrons. Therefore, the 1p orbital doesn't exist. In the second shell, both 2s and 2porbitals exist, as it can have a maximum of 8 electrons. ... Therefore, the 3f orbitals donot exist

From me ☻︎

For the second shell (n=2) d sub-shell cannot exist i.e. there is no existence of d orbital. ... Similarly when n=3, l will have the values of 0,1,2. Naturally there is no existence of f sub-shell in the Shell number 3; i.e. 3f and 2d orbital will be non-existent...
