Atomic+Theory



On this page you will include information to address different atomic theories and their significance in the discovery of subatomic particles.
 * Describe the composition of the atom and the experiments that led to that knowledge.
 * Describe how Rutherford predicted the nucleus.
 * Describe the composition of the atom and the experiments that led to that knowledge.
 * Describe how Rutherford predicted the nucleus.
 * Describe the electron cloud of the atom in terms of a probability model.
 * Explain that Niels Bohr produced a model of the hydrogen atom based on experimental observations. This model indicated that:
 * an electron circles the nucleus only in fixed energy ranges called orbits;
 * an electron can neither gain or lose energy inside this orbit, but could move up or down to another orbit;
 * and that the lowest energy orbit is closest to the nucleus.
 * Recognize the historical contribution that this model gave to our modern theory of the structure of the atom; however, also realize the limitations of this model (applicable only to the hydrogen atom).
 * Describe the wave/particle duality of electrons.
