Integrated Physics and Chemistry Unit 3B

Big Idea:

How matter can be combined, reacted, and organized.

Student Expectations:

Priority TEKS

I.6A Examine differences in physical properties of solids, liquids, & gases as explained by the arrangement & motion of atoms, ions, or molecules of the substances & the strength of the forces of attraction between those particles.

I.6D Relate the physical & chemical behavior of an element, including bonding & classification, to its placement on the periodic table.

I.7B Recognize that chemical changes can occur when substances react to form different substances & that these interactions are largely determined by valence electrons.

Student Learning Targets:

I will use the arrangement & motion of molecules to explain properties of compounds.

• I can explain why molecules have certain properties based on their motion and their internal structure.

I will explain how valence electrons affect the formation of molecules.

• I can explain how atoms use valence electrons to bond together.
• I can use electronegativity differences to explain ionic & covalent bonding.
• I know the similarities and differences between ionic & covalent bonds.

I will use the periodic table to predict the behavior of elements when they are alone or combined.

• I can use the Periodic Table to predict how many electrons atoms will gain or lose when bonding & to determine the oxidation number of an element.
• I can explain why some elements covalently bond.
• I can predict which elements will use ionic bonds.
• I can write formulas for compounds.
• I can write names for simple compounds
