The maximum number of electrons present in the $N$ shell is:

The atomic number of an element is $35$. What is the total number of electrons present in all the $p-$ orbitals of the ground state atom of that element?

What is the maximum number of electrons that can be accommodated in a shell with principal quantum number $n = 4$?

Arrange the following orbitals in increasing order of energy based on the given values of principal quantum number $(n)$ and azimuthal quantum number $(l)$:
$(1) n = 4, l = 1$
$(2) n = 4, l = 0$
$(3) n = 3, l = 1$
$(4) n = 3, l = 2$

The number of radial nodes and angular nodes of a $4f$-orbital are respectively:

The value of the azimuthal quantum number for electrons present in the $4p$ orbital is:
