The important point of the solution of the wave equation is that it provides a set of numbers called quantum numbers which describe energies of the electron in atoms, information about the shapes and orientations of the most probable distribution of electrons around nucleus. The space in which there is maximum probability of finding an electron is termed as orbital. It describes the probability of finding an electron within a small space. Significance of ψ2: ψ2 is a probability factor. ![]() But the probability must be always positive and cannot be negative, it is thus, proper to use ψ2 in favour of ψ. When the equation is solved, it is observed that for some regions of space the value of ψ is negative. The main aim of Schrodinger equation is to give solution for probability approach. ![]() ![]() The wave function may have positive or negative values depending upon the value of coordinates. Significance of ψ The wave function may be regarded as the amplitude function expressed in terms of coordinates x, y and z. V = potential energy of the electron h = planck’s constant and zψ (psi) = wave function of the electron. Where x, y, z are certain coordinates of the electron, m = mass of the electron E = total energy of the electron. Schrodinger derived an equation which describes wave motion of an electron. This model describes the electron as a three dimensioinal wave in the electronic field of positively charged nucleus. This was developed by Ervin Schrodinger in 1926. The atomic model which is based on the particle and wave nature of the electron is known as wave or quantum mechanical model of the atom.
