Paragraph for Next 3 Questions The wave function,$\psi_{n,l,m_l}$is a mathematical function whose value depends upon spherical polar coordinates ($r, \theta, \phi$) of the electron and characterized by the quantum numbers$n, l$and$m_l$. Here$r$is distance from nucleus,$\theta$is colatitude and$\phi$is azimuth. In the mathematical functions given in the Table,$Z$is atomic number and$a_o$is Bohr radius.
