Which of the following ions does not have the electronic configuration of neon $(Ne)$?

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

Five valence electrons of $P^{15}$ are labelled as $\boxed{AB}_{3s} \,\boxed{X|Y|Z}_{3p}$. If the spin quantum numbers of $B$ and $Z$ are $+\frac{1}{2}$,the group of electrons with three of the quantum numbers $(n, l, m)$ the same are:

The correct set of four quantum numbers for the valence electron of rubidium atom $(Z=37)$ is:

The azimuthal quantum number defines:

The rule which states that an electron enters the sub-shell for which the $(n + l)$ value is minimum is known as:
