Solution

## The correct option is A l = 0, 1, 2. ; m = 0,+1,-1,+2,-2When the value of principal quantum number n is 3 the permitted value of azimuthal quantum numbers l and magnetic quantum numbers 'm' are l = 0, 1, 2 m = 0,+1,0,-1,+2,+1,0,-1,-2For a given value of the principal quantum number, the azimuthal quantum number l can values 0,1 ,2....n-1.For a given value of azimuthal quantum number, the magnetic quantum number m can take values −l,.....−2,−1,0,+1,+2.....+l
