WebApr 12, 2024 · The Bohr model of the atom was proposed by Danish physicist Niels Bohr in 1913. It is a visual representation of the atom that shows the electrons orbiting the nucleus in specific energy levels or shells. The Bohr model is a useful tool for understanding the structure of atoms, and it can be used to. 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. photo wattpad
