Problem
An electron in the Li2+ ion is in the fourth stationary orbit (n=4).
(a) Calculate the radius of this orbit in ångströms.
(b) Determine the kinetic energy, potential energy and total energy of the electron in this orbit in electron-volt.
(c) Find the time period of revolution of the electron in this orbit and express it in femtoseconds (1fs=10−15s).
