CHEM 1211 Lecture Notes - Lecture 2: Atomic Theory, Long Term Ecological Research Network, Distillation
Document Summary
The properties of matter are determined by the properties of atoms and molecules ex. The properties of blank molecules determine how blank behaves. Atoms: sub-mircoscoptic particles that are the fundamental building blocks. > change one atom and what you have changes. > not only if you change the number of atoms does the molecule change, but if you change the structure the molecule changes ex. Diamonds and graphite are both made of carbon sheets, the difference is in diamonds the sheets are bound together, and they are not bound in graphite. Chemistry: science that tries to understand the behavior of matter using the behavior of atoms and molecule. Hypothesis: tentative interpretation of observations;good one is falsi able. Experimentation: highly controlled procedures designed to generate observations that con rm or refute a hypothesis. Results can support or deny it -> if denied must modify or discard hypothesis. Scienti c law: brief statement that summarizes past observations and predicts future ones ex.
