Unit 10

Essential Question(s):

How does the shape of compounds and molecules effect their chemical properties?

How does the change in state of a substance effect its chemical composition and properties?

Standard(s):

• HS-PS1-1 Matter and its Interactions

Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

• HS-PS1-2 Matter and its Interactions

Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.

• HS-PS1-7 Matter and its Interactions

Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.

"I can" Statements:

• Draw electron dot structures.
• Use the VSEPR Theory to predict the shape of a compound.
• Use the electronegativity of an element to determine its polarity.
