WebOct 19, 2024 · This picture of the hydrogen atom is wrong in two senses. First it doesn’t conform to our present understanding of the hydrogen atom. This, in itself, is not a reason to scrap it, for the historical development of quantum physics is certainly of interest. ... Niels Bohr and the Quantum Atom: The Bohr Model of Atomic Structure 1913-1925 ... WebIt's all in the definition. The energy is defined as zero when the electron is an infinite distance from the nucleus. As the electron comes closer, the energy decreases, so the energy of the system becomes negative. Even for an H atom in an excited state, the energy is negative, but it is less negative than for an atom in the ground state. onpoint credit card rewards
