An tomic obital has n=3 , what are the possible values of ` l and m_(l)` ?
(ii) List the quantum numbers `(m_(l) and l)` of electrons for 3d orbital .
(iii) which of the following orbitals are possible ?

Explanation

i. `n=3," " l=0, I, 2`
`l=0," " m=0`
`l=1," " m=-1, 0, +1`
`l=2, " "m=-2, -1, 0, +1, +2`
ii. `l=2," " m=-2, -1, 0, +1, +2`
iii. `2s, 2p`
