How many values of magnetic quantum number are possible for each value of azimuthal quantum number?

Explain the energy order of orbitals in multielectron atoms.

The maximum number of electrons that can be accommodated in $f$ subshell is

If an electron has a spin quantum number of $+ \frac{1}{2}$ and a magnetic quantum number of $- 1$,it cannot be present in an

An electron is in one of the $3d$ orbitals. Give the possible values of $n, l,$ and $m_l$ for this electron.

Consider the following statements:
$(a)$ Electron density in the $XY$ plane in $3d_{x^2-y^2}$ orbital is zero.
$(b)$ Electron density in the $XY$ plane in $3d_{z^2}$ orbital is zero.
$(c)$ $2s$ orbital has one nodal surface.
$(d)$ For $2p_z$ orbital,$YZ$ is the nodal plane.
Specify True or False.
