In the Bohr model of the hydrogen atom, the electron occupies distinct energy states. In one transition between energy states, an electron moves from n=1 to n=2. Is energy absorbed or emitted in the process? Does the electron move closer to or farther from the nucleus?
In J. J. Thompson’s experiment depicted in Figures 1.10 and 1.11, assume that the electrons are initially traveling at a speed of 8.00106ms1 in the +x direction and the electrostatic plates have a length of l=0.10m , between which the electrons are deflected toward the -y direction (downward) by an electric field of magnitude 200Vm1 . (Note that 1volt=1V=1JC1 .) Calculate S, the magnitude of the downward displacement, if the fluorescent screen is located 0.90 m beyond the exit of the region between the two electrostatic plates. No magnetic field is applied to counteract the electrostatic force. (Caution: L is not 1.0 m nor 0.9 m; see Figure 1.11.)
The atomic masses of the natural isotopes of neon are 19.99244u, 20.99395u, and 21.99138u . The average of these three masses is 20.99259u . The atomic mass of neon is listed as 20.1797u on the periodic table. Which isotope do you expect is the most abundant in nature? Explain. When neon gas is within an activated gas discharge tube, reddish-orange light is emitted.
We learned about three different models describing a stable atom. Inthree to five sentences, answer the following questions. Use any figures or sketchesif necessary.a) Describe why the Rutherford’s planetary model is wrong.b) What is the basic hypothesis to solve for the Bohr model?c) What is the major limitation of the Bohr model and why?d) Without doing any calculation, briefly state how one can solve theSchrödinger equation for a hydrogen atom?e) Briefly describe how can one use the solved electronic wavefunctionfor a hydrogen atom?
Describe Rutherford’s nuclear model of the atom. What was revolutionaryabout his model?
The Quantum Mechanical Model of the atom was proposed by:
Compare and contrast the contributions of J. J. Thomson, Ernest Rutherford, and Neils Bohr in a Venn diagram. Remember that the overlapping sections of thecircle are for similarities and the non-overlapping sections are for differences. Use all the words in the word box and their experimental conclusions.
Show that Rutherford's experiment can be explained by Rutherford's atomic model
Use a periodic table to draw basic Bohr models (do not include all electrons, only valence electrons. Also, do not draw all parts of a nucleus, only indicate the number of protons in the center.
