The equation of Schroedinger for the hydrogen atom in the time-independet, non-relativistic form is a partial differential equation involving the position coordinates (x, y and z). The potential energy term for the proton-electron system is spherically symmetric of the form -1//4pi in_(0) xx (e^(2)//r) . THus it is advantages to change over from the cartesian coordinates (x,y and z) to the spherical polar coordinates, (r, theta and phi ). In this form the equation become separable in the radial part involving r and the angular part involving theta and phi . The probability of locating the electron within a volume element d tau = 4pi r^(2)dr is then given |Psi|^(2)(4pir^(2)dr) , where Psi is a function of r, theta and phi . With proper conditions imposed on Psi , the treatment yields certain functions, Psi , known as atomic orbitals which are solutions of the equations. Each function Psi correspods to quantum number n, l and m, the principal, the azimuthal and the magnetic quantum number respectively, n has values 1, 2, 3,...., l has values 0, 1, 2, ....(n-1) for each value of n and m (n-1) for each value of n and m (m_(l)) has values =1, +(l+1),...1,0,-1,-2...-l i.e., (2l+1) values for each value of l.

The sinle quantum number by Neil.s Bohr and the appearance of several spectral lines in a particular series of Hspectrum, suggest that there more than one quantum to explain all the quantized properties of an electron in a particular energy level inside the atom. If fact when the properties of the electron is transformed from Cartesian co-ordinate to polar co-ordinates then it becomes the function of r, theta and phi suggesting three independet quantum numbers. In addition to this a fourth quantum number is required to consider the spinning behaviour of an electron. The principal quantum number n suggest the orbit number in which electron revolves, Azimuthal quantum number 1 suggest the shape of orbitals, magnetic quantum number m, gives orientation of orbital in presence of external magnetic field, while spin quantum number s, gives direction of an electron about its own axis n != 0 values of "1" ranges in between 0 to (n-1), while m depends upon 1.
