In a 1911 paper, Ernest Rutherford said: In order to form some idea of the forces required to deflect an alpha particle through a large angle, consider an atom containing a point positive charge Ze at its center and surrounded by a distribution of negative electricity, – Ze uniformly distributed within a sphere of radius R. Derive an expression for the magnitude of the electric field at the center of the atom. - Express your answer using the parameters +Ze and -Ze.

16. Rutherford's experiment with gold estimated the radius of a gold atom to be approximately 1 x 10⁹ cm. Suppose the radius of the nucleus is the same as a basketball. Would the volume of the atom be bigger or smaller than that of a typical domed athletic stadium? Show a little math to support your answer.
1. Marie Curie was a Polish scientist that specialized in chemistry and physics. She wanted to understand how X-rays worked and noticed in her studies that the element, Uranium, gave off rays that could be measured but did not know what the rays were. She assumed that the rays came from the uranium itself instead of through different molecules interacting with each other. To study the rays, she used an instrument, called an electrometer, that studied the electricity that the rays passed through the air. Through this she was able to discover that the more uranium atoms there were in a compound, the stronger the rays that came off of it. She used this discovery to test other minerals that emitted more rays than Uranium, and discovered the elements Thorium, Polonium and Radium. Through her discoveries of these elements, scientists were able to find the structure of the atom and even how the rays can be used to fight cancer. What was Marie Curie’s observation? 2.

A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the following data on the isotopes of molybdenum in these samples: mass relative isotope (amu) abundance 96- Мо 95.9 41.% 91 Mo 59.% 96.9 Use these measurements to complete the entry for molybdenum in the Periodic Table that would be used on 98765 ALEKS. Be sure your answers have the correct number of significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for molybdenum in the Periodic Table we use here on Earth. Mo
Predict which one is the most stable nucleus amongst _8 O^16, _8 O^17 and _8 O^18. ( In this case you have to differentiate w.r to A. See A is the variable in the isotope family. Then find the value of A and see which value is this A close to)

Chromium reacts with oxygen to form three different compounds, X, Y and Z. It was found that, for every gram of chromium in Compounds X, Y and Z, there were 0.308 g, 0.462 g and 0.924 g of oxygen, respectively. (a) Show that the above data illustrate Dalton’s Law of Multiple Proportions.(b) Using these data, derive simple formula of compounds X, Y and Z.
