Description:
  • Describe arrangement of elements in the periodic table
  • Explain how atomic mass of an element is determined & amu definition
  • Identify general properties of metals, nonmetals, and metalloids
  • Describe how properties of elements change across a period in the periodic table

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.

Chapter 5.2 Modern Periodic Table

Read Chapter 5.2 The Modern Periodic Table pg 130-138. Outline the reading in your science notebook and include major points and diagrams/tables.
you should focus on the following essential questions:
- How is the modern periodic table organized
-What does the atomic mass of an element depend on
-What categories are used to classify elements on the periodic table
-How do properties vary across a period in the periodic table
