Question

Bohr's model for the hydrogen atoms predicts that the absorption spectra involve ​

Answer 1

Answer:

Niels Bohr explained the line spectrum of the hydrogen atom by assuming that the electron moved in circular orbits and that orbits with only certain radii were allowed. ... This produces an absorption spectrum, which has dark lines in the same position as the bright lines in the emission spectrum of an element.Sep 5, 2020

Explanation:

Niels Bohr introduced the atomic Hydrogen model in 1913. He described it as a positively charged nucleus, comprised of protons and neutrons, surrounded by a negatively charged electron cloud. The atom is held together by electrostatic forces between the positive nucleus and negative surroundings.The evidence used to support the Bohr model came from the atomic spectra. Bohr suggested that an atomic spectrum is created when the electrons in an atom move between energy levels. ... The electrons would then immediately fall back to a lower energy level and re-emit the absorbed energy.

Niels Bohr suggested that electrons in an atom were restricted to specific orbits and has a fixed boundaries around the atom's nucleus. Bohr argued that an electron in a given orbit has a constant energy, thus he named these orbits energy levels.In atomic physics, the Bohr model or Rutherford–Bohr model, presented by Niels Bohr and Ernest Rutherford in 1913, is a system consisting of a small, dense nucleus surrounded by orbiting electrons—similar to the structure of the Solar System, but with attraction provided by electrostatic forces in place of gravity.
