Unit: Chemistry Unit 1:
Structure of Matter, Reactions, Periodic Table
State Standards Covered:
3. Each of the more than 100 elements of matter has distinct properties and a
distinct atomic structure. All forms of matter are composed of one or more of the
elements. As a basis for understanding this concept:
b. Students know that compounds are formed by combining two or more different elements and that
compounds have properties that are different from their constituent elements.
d. Students know the states of matter (solid, liquid, gas) depend on molecular motion.
e. Students know that in solids the atoms are closely locked in position and can only vibrate; in liquids the atoms and molecules are more loosely connected and can collide with and move past one another; and in gases the atoms and molecules are free to move independently, colliding frequently.
5. Chemical reactions are processes in which atoms are rearranged into different combinations of molecules. As a basis for understanding this concept:
a. Students know reactant atoms and molecules interact to form products with different chemical properties.
d. Students know physical processes include freezing and boiling, in which a material changes form with no chemical reaction.
7. The organization of the periodic table is based on the properties of the elements and reflects the structure of atoms. As a basis for understanding this concept:
c. Students know substances can be classified by their properties, including their melting temperature, density, hardness, and thermal and electrical conductivity.
