The graph between $|\psi|^2$ and $r$ (radial distance) is shown below. This represents

Consider the hypothetical situation where the azimuthal quantum number,$l$,takes values $0, 1, 2, \ldots, n+1$,where $n$ is the principal quantum number. Then,the element with atomic number

The number of radial node/s for $3p$ orbital is:

Which of the following sets of quantum numbers is not possible?
