Unformatted text preview: Chapter 13 The Molecular Model of Matter Did you read all of Chap. 13 for today? Did you read all of Chap. 13 for today? a) a) Yes Yes b) b) No No What is a Model? s A useful analogy we can relate to. s They are almost never 100% correct. ifferent models are s Different models are used to describe the same thing at different levels of detail. F4 Corsair Models of Matter s Continuous (Ch 12.7) s Molecular (Ch 13) s Atomic (Ch 14) s Nuclear olar System (Ch 14 ) • Solar System (Ch 14 ) • Bohr (Ch 14) s Quantum (Ch 16) s … Continuous Model s No matter how many times we cut matter in half, it retains its properties. retains its properties. s Can we really go on cutting matter forever? Assumptions of The Molecular Model s All matter is made of distinct, tiny particles which are: • Too small to see with an optical microscope. • Too small to see with an optical microscope. • Different for different materials • In constant motion • Governed by Newton’s laws of motion • Indivisible So What? s Let’s face it, anyone can come up with a theory or model. The proof is in what it can explain and predict....
