n 1910, Ernest Rutherford performed a set of experiments that helped scientists better understand the structure of atoms. He lirected a beam of a particles (small, positively charged particles) at a very thin sheet of gold foil. He made several observation rom the experiments. How did Rutherford interpret the fact that most of the a particles seemed to pass right through the foil? Most of the volume of an atom is empty space so the a particles passed unobstructed through the electron clouds of the atoms. Gold is malleable so the gold atoms moved out of the way of the a particles and allowed them to pass through. The foil was so thin that the a particles were able to pass in between the tiny, solid gold atoms. How did Rutherford interpret the fact that a few of the a particles were deflected at very large angles? The a particles were striking the negatively charged electrons in the gold atoms. The a particles were striking the neutrally charged neutrons in the gold atoms. The a particles were striking the small, positively charged nucleus of the gold atoms.

Characterize the Bohr model of the atom. In the Bohr model, what do we mean when we say something is quantized? How does the Bohr model of the hydrogen atom explain the hydrogen emission spectrum? Why is the Bohr model fundamentally incorrect?
What refinements had to be made in Daltons atomic theory to account for Gay-Lussacs results on the combining volumes of gases?
One of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. Does this apply to Daltons atomic theory? Give examples.

Reaction of 2.0 L of hydrogen gas with 1.0 L of oxygen gas yields 2.0 L of water vapor. All gases are at the same temperature and pressure. Show how these data support the idea that oxygen gas is a diatomic molecule. Must we consider hydrogen to be a diatomic molecule to explain these results?
One of the early models of the atom proposed that atoms were wispy balls of positive charge with the electrons evenly distributed throughout. What would you expect to observe if you conducted Rutherfords experiment and the atom had this structure?
The contributions of J. J. Thomson and Ernest Rutherford led the way to todays understanding of the structure of the atom. What were their contributions?
2.84 Early attempts to arrange the elements often focused on atomic weight. Mendeleev considered a number of properties in addition to atomic weight, so he realized that some elements seemed out of place when ordered by atomic weight. Using the modern periodic table, identify elements for which Mendeleev must have had to switch the order in order to get the correct sequence of elements.
Are the following statements true for the hydrogen atom only, true for all atoms, or not true for any atoms? a. The principal quantum number completely determines the energy of a given electron. b. The angular momentum quantum number, l, determines the shapes of the atomic orbitals. c. The magnetic quantum number, ml, determines the direction that the atomic orbitals point in space.
