Presentation transcript:

65 List the parts of Dalton’s Atomic Theory. Thompson discovered __________ with the _________ ____ experiment. His ____________model stated negatively charged e-s are embedded in positively charged atom. Rutherford discovered the _________ with the ________ ______ experiment. In his model, negatively charged e-s are scattered around the small, dense, ________ charged center that contains most of an atom’s mass. Bohr’s Model shows that electrons can only exist in certain __________ ______ around the nucleus. The farther away from the nucleus the _______ the energy.

Physical vs Chemical

Properties Describes matter Can be observed without changing substance Physical Chemical Describes matter Can be observed without changing substance Density Color Odor Shape Describes how matter reacts When observed changes the substance Reacts with oxygen Will not react with hydrogen

Changes Doesn't change the substance State Changes Physical Chemical Doesn't change the substance State Changes New substance created Rusting
