Q1: In the wave mechanical theory, the maximum of the charge distribution in the ground state occurs for a distance from the nucleus equal to

A first Bohr radius

B second Bohr radius

C third Bohr radius

D either first or second Bohr radius

ANS:A - first Bohr radius

The total charge associated with an electron moving about nucleus in the ground state of hydrogen atom is given by 4p2rr(r)dr. This integrand has a maximum value at r = radius of first Bohr orbit.
