Problem 9

The lithium ion Li²* is a hydrogen-like ion because it has only one electron orbiting around a

nucleus of charge Z=3. This ion can be described using the wavefunction of hydrogen. The

probability density of finding the electron at a distance r from the nucleus is given by the radial

probability density R=47²². What is the radial probability density of finding an electron in the

and

2s orbital at a distance r=100 pm from the nucleus? 200
