The number of orbitals associated with quantum numbers n=5,ms=+12 is:

Choose an option

Show full solutionCorrect option: B
Correct answer
B25

Step-by-step explanation

For n=5   5s, 5p, 5d, 5f  and 5g and subshell is available

In   5s→1 orbital

5p→3 orbital

5d→5 orbital

5f→7 orbital

5g→9 orbital

In each subshell 1 electron of every orbital will belong to m 5 =+ 1 2 So, Total number of orbitals that will be associate with  m 5 =+ 1 2   will be 1+3+5+7+9=25
