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

If $n = 6,$ the correct sequence for filling of electrons will be

Figure $1$ shows the electron density distribution for a $2s$ orbital. Figure $2$ shows the radial wave function plot for a $2s$ orbital. Which of the following points $(A, B, C, D)$ in Figure $2$ most accurately represents the spherical nodal surface as shown in Figure $1$?

$A$: The energy of an electron can be determined by the principal quantum number.
$R$: The principal quantum number $(n)$ determines the possible distance of the electron from the nucleus.

Explain how the energy of an orbital and the extent of shielding in the same shell depend on the shape of the orbitals.

Possible number of orientations of a subshell is
