WebMar 29, 2016 · It is the number of protons of an atom, which determines its atomic number. It is denoted by ‘z’. All atoms of an element have the same atomic number, z. In fact, elements are defined by the number of protons they possess. For hydrogen, z = 1, because in hydrogen atom, only one proton is present in the nucleus. WebA hydrogen atom is the simplest kind of atom with only one electron. When that electron is removed, a positively charged particle should remain. Discovery of the Proton. In 1886 Eugene Goldstein (1850–1930) discovered evidence for the existence of this positively charged particle. WebDuring the 1880s and ’90s scientists searched cathode rays for the carrier of the electrical properties in matter. Their work culminated in the discovery by English physicist J.J. Thomson of the electron in 1897. The existence of the electron showed that the 2,000-year-old conception of the atom as a homogeneous particle was wrong and that in fact the … herring gas meadville
