Question

what is relation between line spectrum and atom? why we take spectrum to understand the arrangement in atom /stability in atom?​

Answer 1

1) Atoms is known as a line spectrum, because the radiation (light) emitted consists of a series of sharp lines. The wavelengths of the lines are characteristic of the element and may form extremely complex patterns. The simplest spectra are those of atomic hydrogen and the alkali atoms

2) 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. The orbit closest to the nucleus represented the ground state of the atom and was most stable; orbits farther away were higher-energy excited states.

Answer 2

Answer:

lines in the spectrumwork due to transitions in which an electron moves from a higher energy orbit with smaller radius the orbit closest to the nucleus represented the ground state of the atom and was most stable orbits farther away were higher energy excited States
