Calculate magnitude of orbital angular momental of an `e^(-)` that occupies 1s, 2s,2p,3d,3p.

Answer

0;`sqrt(2)(h)/(2pi);sqrt(6)(h)/(2pi);sqrt(2)(h)/(2pi)`

Explanation

Orbital angular momentum
`(h)/(2pi)sqrt(l(l+1)`
`"for" 1s, 2s, l=0 " "O.A.M.=0 `
`"for" 2p,=1 " " O.A.M.=(h)/(2pi)sqrt2 `
`for 3d,l=2 " " O.A.M.=(h)/(2pi)sqrt6`
`"for" 3p,l=1," " O.A.M.=(h)/2(pi)sqrt2`.
