- 1. Ernest Rutherford's gold foil experiment led to the discovery of the atomic nucleus. In the experiment, alpha particles were fired at a thin gold foil. Suppose that an alpha particle (charge +2e, mass 6.64 x 10-27 kg) is fired at a gold nucleus (charge +79e) with a kinetic energy of 5.0 MeV. a. Convert the kinetic energy of the alpha particle to joules. b. In order for the alpha particle to be deflected, it must experience an electrostatic repulsion from the gold nucleus that does work to remove it's kinetic energy and change its direction. Determine the distance at which this occurs. (hint- use conservation of energy) C. The radius of a gold atom is 166pm. Does the alpha particle have be "inside" the atom to be deflected?A carbon-14 atom contains a nucleus with 6 protons and 8 neutrons; it would normally be neutral by attracting six electrons, but two electrons are missing. 1. What net charge does this Carbon-14 atom carry? 2. What electric field (direction and magnitude) would you measure while standing distance to the right of that Carbon-14 atom?1. An iron atom has 26 protons, 30 neutrons and 26 electrons. a. What is the total charge of its nucleus? b. What is the total charge of its electrons? c. What is the magnitude of the electric force of attraction between an iron nucleus and its innermost electron id the distance between them is 1.5 x 1012?
- Atoms have an equal number of electrons and protons so are electrically neutral. Atoms that have a net electrical charge are known as "ions". Positive ions - have "missing" electrons Negative ions - have "excess" electrons 3. The net charge of an object can be found be summing the individual charges. Since charge is quantized, all net charges are just an integer multiple of the elementary charge. q-ne where q is the net charge and n is an integer. For example, sodium can be a +1 ion and chlorine can be a -1 ion. What does this mean concerning their charge and structure?
