Document Summary
Assigned reading: text chapter 3. 1 (early atomic theories and the origins of quantum theory) John dalton, jj thomson, robert millikan, ernest rutherford, heinrich hertz, max planck, albert einstein, and neils bohr are all historically important contributors to models of atomic structure. It is important to note each of their contributions can be linked to a new experimental technique that allowed them to collect data and modify the existing atomic model. As technology continued to advance the atomic model continued to be modified and will continue to be changed. In grade 11 chemistry we use the bohr atomic model since it is describes and explains the relationships found between the bohr quantized orbitals and the mendeleev periodic table: The number of energy levels containing electrons equals the row number of the element. The number of valence electrons in an atom equals the group number of the element.
