Question

Match the orbitals of List-I with the nodal properties of List-II:

Answer 1

$\Rightarrow$ The quantum number ${}^{\prime }{l}^{\prime }$ determines the angular nodes number $L="l"$

$\Rightarrow$ Total number of nodes for an orbital is given by $T="n-1"$

$Angularnode\Rightarrow L$

$Radialnode\Rightarrow R$

$R=T-L$

$T\Rightarrow totalnodes$

$\left(A\right)2s\to L=0,T=2-1=1$ $R=1$

$\left(B\right)1s\to L=0,T=1-1=0,R=0$

$\left(C\right)2p\to L=1,T=2-1=1,R=0$

$\left(D\right)3p\to L=1,T=3-1=2,R=1$
