Question
Explain magnetic quantum number.
✓
Answer
Magnetic quantum number $\left(m_1\right)$ : (i) It describes about orbital. (ii) It gives information about 3D configuration of orbitals. (iii) Number of orbitals in subshell $=2 l+1=$ possible values of $m_l$. (iv) $m_l=-l,-(l-1),-(l-2), \ldots \ldots \ldots 0$,$\ldots \ldots \ldots (l-2),(l-1), l$ (v) $l=0(s) m_l=0$, one $s$-orbital $\begin{aligned} l & =1(p) m_l=-1,0,+1, \text { three } p \text {-orbital } \\ l & =2(d) m_l=-2,-1,0,+1,+2, \text { five } d \text {-orbital } \\ l & =3(f) m_l=-3,-2,-1,0,+1,+2,+3, \text { seven }\end{aligned}$
