Question

(i) An atomic orbital has n = 3. What are the possible values of $l$ and $m_1$ ?
(ii) List the quantum numbers ($m_1$ and $l$ ) of electrons for 3d orbital.
(iii) Which of the following orbitals are possible?
1p, 2s, 2p and 3f

Answer 1

(i) The possible values of l and $m_1$ are :
$l{m}_1$
$00$
$1-1,0,+1$
$2-2,-1,0,+1,+2$
(ii) The quantum numbers ($m_1$ and $l$ ) of electrons for 3d orbital are $l=2,m_1=-2,-1,0,+1,+2$.
(iii) $2s,2p$ orbitals are possible.
