What is the significance of discrete energy levels in an atom?.
- A.They allow for continuous energy absorption
- B.They explain why atoms can emit light at specific wavelengths
- C.They indicate the mass of the atom
- D.They show the total number of electrons in an atom
Model answer
What a good answer should say
- They explain why atoms can emit light at specific wavelengths
Explanation
Why this works
Discrete energy levels mean that electrons can only occupy certain energy states, leading to the emission of photons at specific wavelengths corresponding to these transitions.
