Web20 de set. de 2024 · Bohr's Atomic Model. Following the discoveries of hydrogen emission spectra and the photoelectric effect, the Danish physicist Niels Bohr (1885-1962) proposed a new model of the atom in 1915. Bohr proposed that electrons do not radiate energy as they orbit the nucleus, but exist in states of constant energy that he called stationary states. WebIt is the amount of energy that an electron gains when subjected to a potential of 1 volt; 1 eV = 1.602 × × 10 –19 J. Using the Bohr model, determine the energy, in electron volts, of the photon produced when an …

The energy levels are quantized, meaning that only specific amounts are possible. It would be like a ladder that had rungs only at certain heights.
