Question

The probability of finding out an electron at a point within an atom is proportional to the

• A. Square of the orbital wave function i.e., $\Psi^{2}$
• B. Orbital wave function i.e., $\Psi$
• C. Hamiltonian operator i.e., H
• D. Principal quantum number i.e., n

Answer 1

Answer: (A)

Square of the orbital wave function i.e., $\Psi^{2}$

Answer 2

: $\Psi^{2}$ is known as probability density and is always positive. From the value of $\Psi^{2}$ at different points within an atom it is possible to predict the region around the nucleus where electron will most probably be found.
