The maximum distance a molecule has been moved from its normal position by a wave is
a. amplitude.
b. compression.
c. rarefaction.
d. frequency.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?

How many electrons does each element require in its valence shell to become stable?
