7. Compare and contrast Rutherford's model of the atom with
Bohr's original model of the atom (4 points).
b) Compare and contrast Bohr's original model of the atom and
the quantum mechanical model of the atom (4 points).
How many electrons in an atom could have these sets of quantum numbers?
n=2 --> number electrons = ?
n=5, l=2 --> number electrons= ?
n=7, l=1, ml=-1 --> number electrons= ?
Explain how each of the following represented a failure of
classical physics: 1) Rutherford's nuclear atom; 2) the
ultra-violet catastrophe; 3) the photoelectric effect; 4) atomic
emission and absorption spectra.
a) Describe the Democritian model for the atom.
b) Describe the Thomson model for the atom. What experiment led
to its formulation?
c) Describe the Rutherford model for the atom. What experiment
led to its formulation?
d) Describe the Bohr atom. What experimental evidence led to its
formulation?
Rutherford's experiments showed that positive charges in atoms
is not uniformly throughout the atom. Describe his experimental set
up, results and conclusions
How many electrons does a neutral potassium atom have? How
many protons? How many electrons does a neutral fluorine atom have?
What happens in the molecule of potassium fluoride?
