Question

2. How does the existence of line spectra support for
the Bohr model of the atom?​

Answer 1

Answer:

Lines in the spectrum were due to transitions in which an electron moved from a higher-energy orbit with a larger radius to a lower-energy orbit with smaller radius. ... Bohr's model revolutionized the understanding of the atom but could not explain the spectra of atoms heavier than hydrogen.

Explanation:

Because each element has characteristic emission and absorption spectra, scientists can use such spectra to analyze the composition of matter. When an atom emits light, it decays to a lower energy state; when an atom absorbs light, it is excited to a higher energy state.

Bohr Atomic Model. Bohr Atomic Model : In 1913 Bohr proposed his quantized shell model of the atom to explain how electrons can have stable orbits around the nucleus. ... The atom will be completely stable in the state with the smallest orbit, since there is no orbit of lower energy into which the electron can jump.
