Lecture 4 Flashcards
1
Q
what is a particle
A
hard ball of infinitesimally small volume
2
Q
what properties does small matter show
A
both wave and particle properties
3
Q
wave and particle properties = contradictory behavior. what is the behavior called?
A
wave-particle duality
4
Q
compton effect
A
when an x-ray is applied to an electron at rest, the electron gains kinetic energy and the X-ray loses some radiant energy (the frequency of x-ray becomes less)
compton effect is the result of the particle nature of small matter
5
Q
what is probability density
A
a region of space where a type of small matter (such as an electron is likely to be found (w/ 90% certainty)
6
Q
what is degeneracy
A
a single energy level may have multiple atomic orbitals
