Question

State True or False.

The radial wave function for the ground state of $H$-atom decreases exponentially towards zero as $r$ increases.

• A. True
• B. False

Answer 1

The correct option is A True

The given statement is True.
The radial wave function for the ground state of H-atom decreases exponentially towards zero as r increases.
For 1s orbital of H atom (ground state energy level), the radial wave function (R) is given by the expression $R_{1s}=K_{1s}{e}^{-r/a_0}$
