Web12 sep. 2024 · Figure 8.2.1: A representation of the Bohr model of the hydrogen atom. With the assumption of a fixed proton, we focus on the motion of the electron. In the electric field of the proton, the potential energy of the electron is. U(r) = − ke2 r, where k = 1 / 4πϵ0 and r is the distance between the electron and the proton. He produced solid hydrogen the next year. Deuterium was discovered in December 1931 by Harold Urey, and tritium was prepared in 1934 by Ernest Rutherford, Mark Oliphant, and Paul Harteck. Heavy water, which consists of deuterium in the place of regular hydrogen, was discovered by Urey's group in 1932.
