2 cards from this section. Quick, good the night before a test.
What is an emission spectrum?
Think about the light seen when gas is excited.
What do we call the light particle emitted during transitions?
It’s a fundamental unit of light.
What happens to an electron when an atom absorbs energy?
Consider what happens before they emit light.
True or False: Emission spectra are continuous.
Think about the nature of the observed lines.
An electron in a hydrogen atom moves from n=5 to n=3. Calculate the wavelength of the emitted photon using R_H = 1.0968 × 10^7 m⁻¹.
Remember to apply the Rydberg formula.
Discuss the implications of discrete emission spectra in understanding atomic structure.
Consider how this knowledge translates into practical applications.
