How is the periodic table related to electron configuration and dot diagrams?

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 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 answer questions about electron configurations of atoms and ions and explain how an atom is an exception to the aufbau principle.

Content Standards being covered:

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