The Aufbau principle is not satisfied by which of the following pairs of elements?

Number of completely filled orbitals in xenon atom $(Xe)$ is

The number of radial nodes in $3s$ and $2p$-orbitals,respectively are

The maximum probability of finding an electron in the $d_{xy}$ orbital is

How many maximum electrons can be accommodated in a $p$-orbital with $n = 6$ and $m = 0$?

Select the correct statements for quantum numbers.
$(i)$ Magnetic quantum number $(m_l)$ gives information about the spatial orientation of orbitals with respect to the standard set of coordinate axes.
$(ii)$ Electron spin quantum number is represented by '$s$' and has values of $\pm \frac{1}{2}$.
$(iii)$ Principal quantum number $(n)$ determines the size of the orbitals and also,to a large extent,the energy of the orbitals.
