$ns-$orbital has $(n + 1)$ nodes.

Vedclass · Answer

(B) For any orbital,the total number of nodes is calculated as $(n - 1)$.Angular nodes are given by the azimuthal quantum number $l$.Radial nodes are given by $(n - l - 1)$.Total nodes $=$ Radial nodes $+$ Angular nodes $= (n - l - 1) + l = n - 1$.For $p_z-$orbital,the electron density is zero in the $xy-$plane,so it is a nodal plane.Therefore,the statement that $ns-$orbital has $(n + 1)$ nodes is incorrect,as it should be $(n - 1)$ nodes.

List-$I$ (Orbital)	List-$II$ (Radial nodes and nodal plane)
$A$. $2s$	$I$. $1$ Radial node + two nodal planes
$B$. $3s$	$II$. $1$ Radial node + one nodal plane
$C$. $3p$	$III$. $2$ Radial nodes + No nodal plane
$D$. $4d$	$IV$. $1$ Radial node + No nodal plane
