Wednesday, January 13

Sections 4 & 5: Watch and take notes on the first 9 minutes of this video: Lewis Structures and Models. He speaks a bit quickly so you will likely want to watch the video twice. If you are confused, don't stress - we will go over what he's talking about in class, but it is important that you watched the video first!

Section 2H: Watch and take notes on this video: How to Draw Lewis Structures

Section 4: Read pages 175-177 in your textbook. Make sure to take any bold word/phrase and transpose the definition into your notes. Then, answer questions 1-4 on page 177.

*Be prepared for a short ionic compound writing and naming quiz

Monday, January 11

Section 2H: 

• Outline pages 184 (starting with 'Lewis Structures') through 189 in your textbook. 
• Be prepared for a short ionic compound writing and naming quiz
• You may do quiz corrections if you got an 85 or below on the periodic trends quiz. If you need help with them and, therefore, do not think you can get them to me by next class, please email me to set up an appointment. 

Section 5: Read pages 175-177 in your textbook. Make sure to take any bold word/phrase and transpose the definition into your notes. Then, answer questions 1-4 on page 177. 

Friday, January 8

Sections 4 & 5: Complete the worksheet you got in class today (front and back). You should use your textbook (chapter 6, section 3) to complete the backside of the worksheet.

Thursday, January 7

Section 4: Complete the packet we started in class. If you're feeling confused, these two videos should help:
Writing Ionic Formulas
Writing Formulas with Polyatomic Ions

AND/OR come see me during Academic Enrichment tomorrow!

Section 4: At the end of class we started talking about ions and how they combine - this is called ionic bonding! Take notes on this topic by watching this video: Intro to Ionic Bonding

Monday, January 4

Sections 2H & 5: Today at the end of class I was talking about ions. Let's get a more concrete understanding of what I meant! Watch and take notes on this video:
What's an Ion?

Then, try to answer this question:
*In the video he gives examples of sodium and oxygen as ions. If sodium and oxygen were to combine into a compound, what do you think the ration of sodium to oxygen atoms would be? 1:1? 1:2? etc...
Make sure you can justify your answer. If you feel confident, try to write out the chemical formula of this compound. (Example: the chemical formula for water is H2O)
