Class-Wednesday,February 02/10/10

Review:Atomic structure

Students learned about:
Naming Binary Covalent Compounds

Homework:Study class notes.

Reminder:Benchmark test on Friday 02/12/10

Class-Tuesday,February- 02/09/10

Review: Ionic Bonding

Class discussion about the test.

Homework: Write the name of the anions,their symbol,charge and the elements name.

Reminder:Benchmark Test on Friday 02/12/10

Class-Thursday,February 02/04/2010

Review: Atomic Structure

Today students learned about:
Naming of Binary Ionic Compounds

Steps to write the formula:
1.Write the name of the cation first with the appropriate charges( as superscript) and then anion
2. Criss-cross the charges
3. write the formula ( chages as subscript)

Nomenclature:
1. write the name of the cation first as it is
2. write the name of the anion ending with -ide
Ex: NaCl-Sodium Chloride

Reminder:Test on Friday 02/04/10

Class-Wednesday,February 02/03/10

 Compare and contrast Ionic and Covalent bonding. Give an example of each type of bonding
 Station Teaching: Atomic structure

  Reminder: Test on Friday 02/03/10

Class-Tuesday,February- 02/02/10

Review:Ionic Bonding and charge on ions

Today students learned about:
Covalent Bonding- Sharing of electrons(Non Metal+ Non Metal)

• Single Bond- Two atoms share one pair of valence electrons. Ex: F &F
• Double Bond-Two atoms share two pairs of valence electrons Ex: O &O
• Triple Bond-Two atoms share three pairs of valence electrons. Ex:N & N

Homework: With the help of the periodic table make 4 covalent molcule and show the bonding in terms of electrons.

Class-Monday,February 02/01/10

Review:  Ionic Bonding

Students learned about:
Formation of ions/Charge-Depend on the number of valence electrons an atom lose/gain to become stable(like noble gases)

Homework-Illustate the type of bonding in terms of electron movement:
1. NaCl
2.Mg and Cl
3.H and Oxygen
4. Cl and Cl
