Physical Science Chapter 12 part 2
Which of the following might best explain the reason why electrons are restricted to certain energy levels in an atom? a)They behave like restricted waves and are self-reinforcing. b)They are traveling at very high speeds. c)They are interacting with the light around the atom. d)They are out of phase and self-destruct when outside of distinct energy regions. e)They behave like chaotic waves of alternating frequency.
a) They behave like restricted waves and are self-reinforcing.

electromagnetic spectrum
How is the term photon related to the term quantum?
A quantum of light is actually one photon.
Which color of light comes from the higher energy transition, red or blue?
Blue is a higher frequency and therefore corresponds to a higher energy level transition.
What was Niels Bohr's explanation for the observation of atomic spectra?
Electrons could only move in discrete energy steps within an atom.
How can a hydrogen atom, which has only one electron, have so many spectral lines?
One electron can be boosted to many different energy levels.
