Question

what is the value of orbital angular momentum of an electrons in orbitals 1s , 3s , 3d , 2p-

Answer 1

Orbital angular momentum is given by the formula √l(l+1) h/2π

where l =azimuthal quantum number

the value of 'l' depends only on sub shell and not on shell. The value of 'l' for various sub shells are:

s = 0

p = 1

d = 2

f = 3

For a 1s and 3s orbital, l = 0; putting l = 0 in the above expression we get

Orbital angular momentum = 0

For 3d orbital, l = 2; Putting l=2 in the above expression, we get

Orbital angular momentum = √2(2+1) h/2π

                                             = √6 h/2π

For a 2p orbital, l = 1, Hence

Orbital angular momentum = √1(1+1) h/2π

                                             = √2 h/2π

Answer 2

Answer:

1 Hence orbital angulas momentum

=√1(1+1)h/2π

=√2h/2π
