Total number of unpaired electrons in an atom of atomic number $29$ is

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

The wave function $R_{2,0}$ for hydrogen atom is $R_{2,0} = K(2 - r/a_0) \exp(-r/2a_0)$,where $K$ is a constant. The distance $r$ at which $R_{2,0}$ exhibits a nodal point is at:

For a $d$ electron,the orbital angular momentum is
