We introduce a concept of proton cloud and calculate the radius of the protoncloud of the Hydrogen atom. Then, we estimate the radius of the proton cloud ofa Hydrogen atom on highly excited Rydberg states. Based on the size of protoncloud, the stability of the atom and technical level, we guess that the directperceiving of the Hydrogen nucleon cloud, or proton cloud, is possible in nearfuture.

Proton cloud and the possibility of direct perceiving of a Hydrogen nucleon
