Journal Entry:

How is the periodic table organized? What other ways could you organize it?

Learning Intentions

• You will explore properties of elements form the periodic table to discover trends and patterns.

• You will begin to explore the trends for atomic properties such as electron configuration and dot diagrams.

• You will learn how to create Lewis dot diagrams for each atom based on its electron configuration.

• You will learn what the trend is for Lewis dot diagrams on the periodic table.

• You will learn the definitions of a number of atomic properties such as ionization energy, atomic and ionic radius, electronegativity, typical ionic charges, melting and boiling points, and reactivity.

Closing Task:

You can identify the primary elemental properties that form trends on the periodic table and describe those trends.

Content Standards being covered:

Many properties of atoms exhibit periodic trends that are reflective of the periodicity of electronic structure (EK 1.C.1)
