is there any problem in defining this value?
Short Answer TypeLong Answer TypeShort Answer Typeψ is a wave function and refers to the amplitude of electron wave i.e. probability amplitude. It has got no physical significance. The wave function ψ may be positive, negative or imaginary.
[ψ]2 is known as probability density and determines the probability of finding an electron at a point within the atom. This means that if:
(i) is zero, the probability of finding an electron at that point is negligible.
(ii) [ψ]2 is high, the probability of finding an electron is high i.e. electron is present at that place for a long time.
(iii) [ψ]2 is low. the probability of finding an electron is low i.e. electron is present at that place for a shorter time.
