Lesson 2.1 - Ions

             Learning Intention: 

What? We are learning how atoms loses, gains, or shares electrons. 

Why?  In order to better understand how chemical bonds. 

             Success Criteria

I can: 

- Predict, describe, & illustrate which elements gain or lose electrons.  

- Identify the oxidation (charge) number of groups on the PT. 

- Identify Ions as Cation or Anion.

The following slides will be used for Mini Lessons and/or for you to view for more resources as needed. 

What happens to the charge of Na when it LOSES an electron?  What about Cl?  

Na = +1

Cl = -1

  Charges are known as oxidation numbers.

Cations are METALS

Anions are Nonmetals

Ion Notation:  how to write the information for one Ion.

You may see Ions written either of these ways.
