The wave function Phi_(n,l,m_(1)) is a methematical function whose value depends upon shperical upon spherical polar coordinates (r,theta,phi) of the electron and characterized by the quantum numbers, n,l and m_(1).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, a_(0) is Bohr radius. . Q. For the given orbital in column 1, the only correct combination forany hydrogen-like species is:
