Explain in brief the experimental proof which led to the discovery of –
Protons
Is it possible for the atom of an element to have one electron, one proton and no neutron. If so, name the element.
Assertion: Proton can be defined as a hydrogen ion (H+).
Reason: These photons are produced when one electron is removed from one hydrogen atom.
