A hydrogen atom consist of a positively charged nucleus (+e)) and a negatively charged electron (-e). In
quantum physics the electron is described as a "cloud" surrounding the nucleus. In the ground state, the
electron cloud is defined as a continuous charge density.

The nucleus of a hydrogen atom is a single proton, which has a radius of about 1.1 x 10-15 m. The single electron in a hydrogen atom
orbits the nucleus at a distance of 5.3× 1011 m. What is the ratio of the density of the hydrogen nucleus to the density of the complete
hydrogen atom?

It may be argued on theoretical grounds that the radius of the hydrogen atom should depend only on the fundamental constants h, e, the electrostatic force constant k = 1/4πℰ0, and m (the electron’s mass). Use dimensional analysis to show that the combination of these factors that yields a result with dimensions of length is h2kme2.
