Journal Entry:

Looking at the poster you made with the ion cards, where are the atoms that become positively charged ions? Where are the atoms that become negatively charged? How do they get those charges?

Learning Intentions

• We will learn what an ion is and the difference between an anion and cation.

• We will learn the relationship between an ion charge, valence electrons, and an atom's placement on the periodic table.

Closing Task:

You can colored a table of ions to distinguish the cations from the anions and the noble gases.

Content Standards being covered:

Students understand the structure of matter at the atomic level and the history that lead to our current understanding.
