Question

What is the significance of psi and psi square chemistry?

Answer 1

PSI represents the amplitude of the electron wave. It is commonly called wave function. It is a mathematical function and has no physical meaning by itself. Magnitude of psi square has the physical meaning as it determines the probability of density of finding the electron at that point.

Answer 2

Answer:

psi has no  significance and psi square has significance  as it determines the probability density or the region where probability of finding electron is maximum.
