Which of the following is true about the wave function of an electron in an atom?

A.A) It directly gives the position of the electron

B.B) Its square gives the probability density of finding the electron

C.D) It is constant for all electrons in the atom

D.C) It is always real-valued

Explanation

Core Concept

In quantum mechanics, the wave function (ψ) itself does not have a direct physical interpretation. However, the square of the wave function (|ψ|²) gives the probability density of finding the particle at a particular location. Wave functions are generally complex-valued and vary depending on the quantum state of the electron.

Correct Answer

BB) Its square gives the probability density of finding the electron
