Aim: How do chemists define matter Aim: How do chemists define matter? Do Now: Review topics that will be on cumulative final Friday: How to interpret particle diagrams? Distinguishing between matter and energy. Compare and contrast elements, compounds and mixtures. Applying formula to relationship between pressure and volume of confined gases. Applying formula to find out heat associated with reactions. Compare and contrast nuclear fission with fusion. Distinguish between natural transmutation, artificial transmutation, and radioactive decay.

Aim: How do chemists define matter? Describe the characteristics of a chain reaction. Describe the particles and electromagnetic waves that make up radioactive emissions. Explain the statement: “Matter is continuous.” Describe Democritus’ view of the unit of matter. How did Dalton describe atoms? How was Dalton’s work different from that of the ancient Greek philosophers? “Each atom of an element is identical to every other atom of that element. Elements are composed of atoms which are identical in mass.” True or false? Explain.
