Why is Bohr's model of an atom not able to explain the spectrum of atoms other than hydrogen? Can you give an example? :what:
They do not, but Bohr's orbits have a speed.kay said:I don't even know orbitals had speed.
Bohr's model of an atom is a theoretical model proposed by Niels Bohr in 1913, which describes the structure of an atom as a positively charged nucleus surrounded by negatively charged electrons that orbit the nucleus in fixed energy levels.
The main features of Bohr's model include the concept of discrete energy levels, in which electrons can only exist in specific energy states and can jump between energy levels by absorbing or emitting photons. It also introduced the idea of a central nucleus containing protons and neutrons, with the number of protons determining the element's identity.
Bohr's model is different from previous atomic models in that it incorporates the concept of quantized energy levels, which was not included in earlier models such as the Thomson and Rutherford models. It also explains the stability of atoms by proposing that electrons can only exist in specific orbits or energy levels, rather than being able to move freely around the nucleus.
Bohr's model has several limitations, including its inability to accurately predict the behavior of atoms with more than one electron. It also does not account for the wave-like behavior of electrons, which is better described by quantum mechanics. Additionally, it does not explain the existence of subatomic particles such as neutrons and does not account for the concept of electron spin.
Bohr's model was a significant contribution to our understanding of the atom, as it provided a better explanation for the stability of atoms and the spectral lines observed in the emission and absorption of light. It also paved the way for further developments in atomic theory, leading to the development of quantum mechanics and a deeper understanding of the behavior of subatomic particles.
