According to the planetary (or Bohr) model of the
atom, which of the following is true?
Electrons travel in well-defined paths, much as a planet
orbits the sun.
An electron is only one part of an atomic cloud, made up of
positive and negative charges.
Electron positions are considered to
be probabilistic (and determined using wave
functions).
Electrons are made up of smaller particles that travel around
their center, like moons around a planet.
An electron that has been 'promoted' into an excited state will
almost immediately do which of the following?
Remain in the excited state until acted on by an outside
force.
Relax to a lower energy state, emitting a photon
Jump to a higher energy state, absorbing a photon.
