The total number of electrons present in all the $p$-orbitals of bromine is

In an atom,if the $K$-shell has $2$ electrons,the $L$-shell has $8$ electrons,and the $M$-shell has $6$ electrons,what is the total number of electrons in the atom?

The maximum number of electrons that can be accommodated in a shell with $n=4$ is:

Given:
$(A)\ n = 5, m_l = +1$
$(B)\ n = 2, l = 1, m_l = -1, m_s = -1/2$
The maximum number of electron$(s)$ in an atom that can have the quantum numbers as given in $(A)$ and $(B)$ are respectively:

Among the following,the incorrect statement is

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 $:-$
