Overview of Topic:
Chemistry is centered around the interactions between elements, called reactions.  These reactions result in new substances, and combinations of elements, which have different properties together than those of the original elements.  The properties of these new substances may make them valuable to our lives, for useful materials, medicines, or even air purification.​ All of this depends on the teeny-tiny particles called electrons.

Unit Vocabulary:

Essential Questions:

1. Why can’t we make crystals from any substance?
2. Why are chemical names so confusing?​
   
3. How can we use the periodic table to predict reactions?

Learning Objectives:

1. I can describe the properties of an element which allow us to predict reactions..
2. I can use the trends in chemical and physical properties to predict reactions.
   
3. I can craft a prediction and explanation for a reaction based on elemental properties and periodic trends.​

Goal Sheet

Standards Addressed:
​HS-PS1-1. 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: 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.
