What is the similarity between $2p_x, 2p_y$ and $2p_z$ orbitals?

Which electron,$2s$ or $2p$,is more strongly attracted to the nucleus? Explain.

To which orbital among the following may an electron having zero angular momentum belong?

Explain,giving reasons,which of the following sets of quantum numbers are not possible.
$(a)$ $n=0, l=0, m_{l}=0, m_{s}=+\frac{1}{2}$
$(b)$ $n=1, l=0, m_{l}=0, m_{s}=-\frac{1}{2}$
$(c)$ $n=1, l=1, m_{l}=0, m_{s}=+\frac{1}{2}$
$(d)$ $n=2, l=1, m_{l}=0, m_{s}=-\frac{1}{2}$
$(e)$ $n=3, l=3, m_{l}=-3, m_{s}=+\frac{1}{2}$
$(f)$ $n=3, l=1, m_{l}=0, m_{s}=+\frac{1}{2}$

Which of the following set of quantum numbers represents the highest energy of an atom?

Match List-$I$ with List-$II$ :

List-$I$ (Quantum numbers)	List-$II$ (Orbital)
$A$. $n = 2, l = 1$	$I$. $3d$
$B$. $n = 4, l = 0$	$II$. $2p$
$C$. $n = 5, l = 3$	$III$. $4s$
$D$. $n = 3, l = 2$	$IV$. $5f$
