Detailed Solution
Orbital angular momentum =l(l+1)h2πfor 1s orbital, l = 0 thus orbital angular momentum = zerofor 3s orbital, l = 0 thus orbital angular momentum = zerofor 3d orbital, l = 2 thus orbital angular momentum = 2(2+1)h2π=6h2πfor 2p orbital, l = 1 thus orbital angular momentum =1(1+1)h2π=2h2πh2π=h¯
