Answer 4

option D

Answer 5

because if n=2(principal quantum no.) ,the are possible subshells are :-
2s and 2p

Answer 6

and in option d ,l=3 which means its d orbital

Answer 7

therefore,option D is incorrect

Answer 8

Hope you understand. @superhelp101

Answer 9

yes i do so do you know if option A is correct?

Answer 10

Option A is correct,
option a says that this is 2p orbital

Answer 11

Thank you!!!

Answer 12

Always Welcome :)

Answer 13

l can never be greater than n, in option D, l=3 and n=2. So it's incorrect
