a. An atomic orbital has `n=3`. What are the possible values of `l` and `m`?
b. List the quantum numbers `(m_(1) and l)` of electons for `3d` orbital.
c. Which of the following orbitals are possible" `lp, 2s, 2p,` and `3f`?

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`
