Consider the following sets of quantum numbers: Which of the below setting is not permissible arrangement of electrons in an atom?

Answer»

400`-(1)/(2)`
540`+(1)/(2)`
33-2`-(1)/(2)`
32-3`+(1)/(2)`

Solution : For a GIVEN value of .l. the permissible VALUES of .m. are `-I,-(l-l)…0….(l=l),`l
Thus , for `l=2`, m can not have a value of -3
