" The orbital represented by "psi_(4,2,0)" is "

The wave function of an orbital is represented as psi_(4,2,0) . The azimuthal quantum number of that orbital is

One of the major requirement in atomic structure is determination of location of electron inside an atom. The wave mechanical model establishes this in accordance with Heisenberg's uncertainity principle through the concept of orbitals. The orbitals are defined as that '3D' space in which probability of finding electron is maximum and are represented by wave functions Psi_(n,l,m) where n,l and m are quantum number. The variation of Psi is analysed in terms of polar coordinates and hence Psi = f( r, 0 , phi) where 'r' represents radius vector and 0 and phi represents angle (/_) Which the radius vector with x-axis respectively. The expressions of Psi_(r,0, phi) are often given in terms of sigma instead of r where sigma=(2Zr)/(nalpha_(0)) and Z = atomic number and n= shell number. If an orbital is represented as: Psi_(r,0,phi)=2/3((1)/(3alpha_(0)))^(3//2).(sigma-1)(sigma^(2)-8sigma+12) .sigma^(-sigma//2).cos0 belong to which orbital?
