Essential QuestionsWhy does the Earth have Uranium? (Where did the elements come from?)
How has our current understanding of the atom developed over time? How does our current understanding of the atomic theory explain the characteristics of atoms? How do chemists deal with the small masses and huge numbers of atoms and molecules? How is the property of density determined? How can a physical property be used to identify a substance? |
Unit 1: "Finding Order"
Unit Understandings, Themes, and Concepts:
Order can be found in atomic structure. Changes in this order, are the result of energy changes in the system.
Matter is composed of a limited number of elements created through nuclear events in the universe involving tremendous amounts of energy.
Modern atomic theory of the structure and behavior of atoms rests on the combined work of many scientists.
Properties, which are a result of structure, can be used to identify matter and predict its behavior.
The fundamental unit for measuring amount of substance is the mole.
