Explain why the spectrum consists of a series of discrete lines?

Answer 1

e- absorb energy and move to an orbital of higher energy. Falls back down to lower energylevels

releasing the energy. The lines result from the fact that e-'s can only have discrete/quantized energy

levels, they cannot have intermediate energy levels.

Answer 2

The spectrum consists of a series of discrete lines because each line corresponds to a specific energy level transition in the atom or molecule. When an electron moves from one energy level to another, it emits or absorbs a photon with a specific energy corresponding to that transition, leading to the formation of discrete lines in the spectrum.

Answer 3

• When a sample of gaseous atoms of an element at low pressure is subjected to an input of energy, such as from an electric discharge, the atoms are themselves found to emitelectromagnetic radiation.
• On passing through a very thin slit and then through a prism the light (electromagnetic radiation) emitted by the excitedatoms is separated into its component frequencies.

Answer 4

The lines in the spectra arise from an electron dropping to a lower principal quantum number, n.

Answer 5

Because the light is being produced by electrons falling back from and excited state to a normal state and in doing so emitting light at discrete energy levels.

Answer 6

Because of the electrons.
