The shape of $p$-orbital is

For a given value of quantum number $l$,the number of allowed values of $m$ is given by

Which of the following rules or principles states that "No two electrons in an atom can have the same set of four quantum numbers"?

The number of $d$ electrons in $Fe$ is equal to which of the following?
$i$. Total number of '$s$' electrons of $Mg$
$ii$. Total number of '$p$' electrons of $Cl$
$iii$. Total number of '$p$' electrons of $Ne$
The correct option is

Consider the following statements:
$(A)$ The principal quantum number $'n'$ is a positive integer with values of $'n'=1, 2, 3, \dots$.
$(B)$ The azimuthal quantum number $'l'$ for a given $'n'$ (principal quantum number) can have values as $'l'=0, 1, 2, \dots, (n-1)$.
$(C)$ Magnetic orbital quantum number $'m_l'$ for a particular $'l'$ (azimuthal quantum number) has $(2l+1)$ values.
$(D)$ $\pm 1/2$ are the two possible orientations of electron spin.
$(E)$ For $l=5$,there will be a total of $11$ orbitals.
Which of the above statements are correct?
