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

Answer

`(i) l = 0, m_l = 0 ; l = 1, m = -1, 0, + 1; l = 2, m_l = -2 -1, 0, + 1, + 2 (ii) l = 2, m_l = -2, -1, 0 + 1, + 2 (iii) 2s, 2p`
