How does bohr's model explain the simultaneous appearance of a large number of lines in the hydrogen spectrum?
Answers
Answer:
Bohr's model of the hydrogen atom gave an exact explanation for its observed emission spectrum. The following are his key contributions to our understanding of atomic structure: Electrons can occupy only certain regions of space, called orbits. Orbits closer to the nucleus are lower in energy.
Answer:
This is the answer
Explanation:
Bohr tells us that the electrons in the Hydrogen atom can only occupy discrete orbits around the nucleus (not at any distance from it but at certain specific, quantized, positions or radial distances each one corresponding to an energetic state of your H atom) where they do not radiate energy.
When the electron moves from one allowed orbit to another it emits or absorbs photons of energy matching exactly the separation between the energies of the given orbits (emission/absorption spectrum).
We see these photons as lines of coloured light (the Balmer Series, for example) in emission or dark lines in absorption.
