Which orbital among the following has zero radial nodes and $2$ angular nodes?

The electrons would go to lower energy levels first and then to higher energy levels according to which of the following?

"Pairing of electrons in the orbitals belonging to the same subshell does not occur unless each orbital belonging to that subshell has got one electron each." This statement is known as

Match the column:

Column-$I$	Column-$II$
$A$. The orbital which has two angular nodes	$P$. $4d_{x^2-y^2}$
$B$. The $d$ orbital with zero nodal plane	$Q$. $3d_{z^2}$
$C$. The orbital with two radial nodes	$R$. $4f$
$D$. The orbital with three angular nodes	$S$. $3s$

Correct match will be $:-$

The maximum number of electrons in a $p$-orbital with $n = 5$ and $m = 1$ is

When the principal quantum number is $n = 3$,the possible values of the azimuthal quantum number $(l)$ are:
