Which of the following quantum number combinations is not allowed in an atom? n= 2, l= 1, m= 0 n= 1, l= 0, m= 0 n= 4, l= 3, m= -3 n= 2, l = 3, m= 2

OpenStudy (mayankdevnani):

option D

OpenStudy (mayankdevnani):

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

OpenStudy (mayankdevnani):

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

OpenStudy (mayankdevnani):

therefore,option D is incorrect

OpenStudy (mayankdevnani):

Hope you understand. @superhelp101

OpenStudy (superhelp101):

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

OpenStudy (mayankdevnani):

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

OpenStudy (superhelp101):

Thank you!!!

OpenStudy (mayankdevnani):

Always Welcome :)

OpenStudy (abhisar):

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