Are you trying to find the deBroglie wavelength of the electron when it is in the first excited state? If so, the formula E = hc/λ is not the correct formula.Suyash Singh said:when i use E=-13.6 (z/n)^2
and then use E=hc/lamda(wavelength)
then wavelength is coming wrong
The Bohr orbit, also known as the Bohr model, is a simplified model of the electron's movement around the nucleus in an atom. It was proposed by Danish physicist Niels Bohr in 1913 and is based on the idea that electrons orbit the nucleus in specific energy levels, or shells, and can jump between these levels by absorbing or emitting energy.
The Bohr orbit is a simplified version of the modern atomic model, which is based on quantum mechanics. In the modern model, the electron's position cannot be precisely determined, and it is described by a probability distribution rather than a definite orbit. Additionally, the modern model includes more complex energy levels and sublevels, whereas the Bohr model only has a few discrete energy levels.
The Bohr orbit was a significant development in the understanding of atomic structure and helped to explain the spectra of atoms. It also laid the foundation for further advancements in quantum mechanics and our understanding of the behavior of electrons in atoms.
The Bohr orbit explains the stability of atoms by proposing that electrons can only occupy specific energy levels, and they do not emit energy while in these stable levels. This idea was revolutionary at the time, as it contradicted classical physics, which suggested that orbiting electrons should continuously lose energy and eventually spiral into the nucleus.
No, the Bohr orbit is a simplified model and does not accurately predict the behavior of all atoms. It works well for atoms with only one electron, such as hydrogen, but fails to explain more complex atoms. The modern atomic model is a more accurate description of atomic behavior and is used to predict the behavior of all atoms.
