Believed that matter was composed of tiny indivisible particles called atoms. Daltons Atomic Theory 2. all atoms of a given element are exactly alike. 2) Atoms of one element are identical while atoms of different elements are different. Atomic Theory Timeline The atomic model has changed over time. Dalton's theory also said that atoms of the same element were the same, while atoms of different elements were different. 3. in a particular compound, atoms of different elements always combine in the same way. II. Prof. Sadoway talks about the principles of modern chemistry and how that led to the understanding of the structure of the atom.He details Bohr's postulates for the hydrogen atom and discusses how the Planck-Einstein relationship applies to electron transitions. We have this much energy going in, the metal itself requires this much energy, the work function, in order to eject an electron. Quantum Theory of the Atom. He formulated the first atomic theory since the "death of chemistry" that occurred during the prior 2000 years. PROTONS- positive electrical charge, found in the NUCLEUS, or center of an atom.
