Document Summary
Notes for lecture #1 (w sept 9): introduction; matter & atomic theory. Key concept 2-a: outline the experiments revealing the basic structure of the atom and know the definitions of atomic number, mass number, and net charge (practice questions. 1 & 2 for hw 2 learning activities) Key concept 2-a: outline the experiments revealing the basic structure of the atom and know the definitions of atomic number, mass number, and net charge. In this experiment each drop was found to have a charge which is an integer multiple of. Thomson"s experiment, millikan"s results led to the conclusion that the rest mass of an e- is. Combined with the results of m = 9. 11 10-31 kg. Key concept 2-b: based on the definitions of atomic number, mass number, and net charge, use the periodic table of elements to find the numbers of neutrons, protons, and electrons in an isotope from its standard atomic symbol.
