# Why does ψ^2 ( square of orbital wave function ψ) give the probability of an electron in a given region? [duplicate]

Today I was introduced to the Orbital Wave Function for electrons. $$\Psi$$ is a mathematical function for coordinate of electrons and has no physical meaning. But $$\Psi^2$$ gives probability of an electron. How does a function for coordinate give probability distribution when squared ? How is the $$\Psi$$ working ?

Please explain me in easier to understand terms with out monster equations.

• What's the monstrous equation (Schrödinger's equations)? And state of the particle is completely described by $\Psi$, it got it's meaning.. doesn't $\Psi^2$ gives probability density? Feb 29 '20 at 19:00

• @Zenix yes! I don't really understand it. I suppose it relates the various energies of the particle with its coordinates. Am I right? Feb 29 '20 at 19:15

• "Today I was introduced to the Orbital Wave Function" - well that suggests that you already know more then you really need on your level of education, and teacher didn't tell you how it work for good reasons. Feb 29 '20 at 19:49
