WebJun 8, 2024 · The Bohr model shows the atom as a central nucleus containing protons and neutrons with the electrons in circular orbitals at specific distances from the nucleus. These orbits form electron shells or energy levels, which are a way of visualizing the number of electrons in the various shells. WebAug 15, 2005 · In the model, the three configurations 1, 2, 3 with the electrons on opposite sides of the internuclear axis (φ = π) are seen to correspond to singlet states, whereas the other solution 4 with the electrons on the same side (φ = 0) corresponds to the triplet state. WebWhich statement below does NOT follow the Bohr Model? A. When an atom emits light, electrons fall from a higher orbit into a lower orbit. B. Electrons exist in specific, quantized orbits. C. None of the above D. When energy is absorbed by atoms, the electrons are promoted to higher-energy orbits. E. The energy emitted from a crystal fairy flyer
