SUMMARY

A hypothetical atom with five energy levels can produce a total of 10 emission lines. When an electron transitions from the fifth energy level, it can emit photons by dropping to any of the four lower levels: 4, 3, 2, or 1. The number of emission lines is calculated using the formula n(n-1)/2, where n is the number of energy levels. Therefore, for five energy levels, the calculation yields 10 distinct emission lines.

PREREQUISITES
  • Understanding of atomic structure and energy levels
  • Familiarity with electron transitions and photon emission
  • Knowledge of combinatorial mathematics, specifically the formula for combinations
  • Basic principles of spectroscopy and emission spectra
NEXT STEPS
  • Research the concept of electron transitions in quantum mechanics

A hypothetical atom has five energy levels. How many emission lines will it produce?
 
Physics news on Phys.org
If an electron excites to fifth energy level, It will transit to 4 or 3 or 2 or 1. Similarly find the number of emission lines from other energy levels.
