Question

What does ${\psi }^2$ represents in the quantum model of atom?

• A. Density of electron
• B. Probability of finding the electron
• C. Volume of electron
• D. Distance of electron from Nucleus

Answer 1

Answer: (B)

Probability of finding the electron

The square of the wave function ${\psi }^2$ represents the probability of finding the electron at various places in a given region around the nucleus. ${\psi }^2$ varies from one region of space to another. Hence, the probability of finding electron in different regions is different. This is in accordance with uncertainty principle.
