Concept Introduction:
Erwin Schrödinger gave a model to describe the behavior of an electron in atoms through a wave function. The wave function is defined as a mathematical function for an electron wave that gives the amplitude of the wave at any point in space. It is represented by a Greek letter
The wave function of an electron has no physical significance but when the square of its absolute magnitude takes then it gives a probability of finding the electron at any particular point of time.
The expression of the probability of finding electrons is as follows:
The acceptable wave function is characterized by a set of four quantum numbers. These quantum numbers are related to the shape, size of the electron wave and the location of the electron in space.
