Atoms - answer-fundamental submicroscopic unit of all mass. Size of the atom and its weight have interested scientists for a long period. Subsequently, experiments were devised to determine the size and weight of the various atoms. The lightest of all atoms is hydrogen. Proton - answer-a subatomic particle having a positvie charge identical in magnitude to the negative charge of an electron and, together with the neutron, a component of all atomic nuclei. The proton forms, by itslef, the nucl...
