1a. Draw a picture of JJ Thomson experiment and explain (a set of phrases is fine) what he did and what happened.<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> 1b. What did the results of his experiment explain with respect to atom.<br> <br> <br> <br> 1c. What is the model of the atom called as a result of Thompson experiment _________________?. What did it say?<br> <br> <br> 9a. Millikian did an experiment with __________________ and from his results in the experiment determine the electron's actual ___________ (results also determined the actual charge of electron). <br> 9b. Fill in below <u>actual mass</u>, (charge) and location in atom.<br> 9bi. Proton ( p ) _______________________ , ( ) and <br> 9bii.Electron ( e ) _______________________ , ( ) and <br> 9biii. Neutron ( n ) _______________________ , ( ) and <br> <br> 10. _________________________ (name of scientist) discovered the proton.<br> <br> 11. _________________________ (name of scientist) discovered the neutron (not until many years later: 1930s).<br> <br> 12a. In the space below, draw a picture of Rutherford's Gold leaf Experiment (label all parts).<br> <br> <br> <br> <br> <br> <br> 12b. In the lines below, briefly explain how his experiment worked.<br> <br> ______________________________________________________________________________________________<br> <br> ______________________________________________________________________________________________<br> <br> ______________________________________________________________________________________________<br> <br> <br> 12c. Rutherford said that nucleus is ___________________, __________________, and ______________ charged region of space in the atom. <br> 12d. What happened to the alpha particle (his bullet) when it got to the nucleus to indicate that the nucleus is: <br> 12di. High mass ________________________________ and<br> 12dii. Very small volume compared to volume of atom __________________________<br> 12e. In the space below, draw a picture of the structure of the atom (Rutherford's).<br> <br> <br> <br> <br> 12e. From the results of Rutherford's experiment. what do we know about the location of the electron? _____________________<br> <br> <br> 13a. Bohr model of the atom (sometimes called the planetary model) improves on Rutherford's work by explain about the location or pathway of which subatomic particle _______________<br> <br> 13b. Bohr's model of the atom has a coordinate system that means the _________ of an electron equals ( = ) the ___________ of electron.<br> <br> 13c. Draw a picture of Bohr's model of the atom.<br> <br> <br> <br> <br> <br> <br> 13d. In the space below, explain how the atom absorbs energy. Please include information about the atom and the electrons.<br> <br> _______________________________________________________________________________________________<br> <Br> _______________________________________________________________________________________________<br> <br> _______________________________________________________________________________________________<br> <br> 13e. What is the incorrect part of Bohr's model of the atom?<br> <br> ________________________________________________________________________________________________<br> <br>
