Question

1. Explain how a bright-line spectrum is produced, in terms of excited state,
energy transitions, ground state and subatomic particles?

Answer 1

Answer:

energy released - excited to ground -An electron absorbs energy and moves to a higher shell (energy level). As the electron returns to a lower shell (energy level), it releases energy in the form of a bright- line spectrum.

Answer 2

The characteristics of the atomic models that the energy levels are discrete allow to explain the existence of bright lines in the emission spectra is:  

• The bright lines are the jump between two energy levels of an atom.

The energy levels of the atoms were initially explained by Bohr's model and later fully resolved and explained by quantum mechanics, in all these models they are discrete levels and there is nothing between them.

When the atoms are in their base state, all the electrons occupy the different levels allowed, before some excitation one of the electrons jumps from one level to another higher, after a period of time this electron falls back to the lower levels directly or by jumps if there are empty intermediate allowed levels, in each fall jump a little energy is released, this is the bright lines in the atomic spectra

The energy of the bright lines matches the difference in energy between the two levels involved.

In conclusion, the characteristics of the atomic models that the energy levels are discrete allow you to explain the existence of bright lines in the emission spectra.  

• The bright lines are the jump between two energy levels of an atom.
