Lesson Plan for week ending 0309

Monday:
 
0305BW: Ions that are made of more than one atom are called polyatomic—poly means “many.” When a neutral atom transfers one or more electrons to another atom, it results in the formation of an ionic compound. Pages 365 to 366
0305CW: Read pages 365, 366 Complete fill-ins. Complete the figure 3 activity on class work paper. Draw the elements as models and show their electron interaction.
00305HW: What is the formula to combine Calcium, Ca, with Chloride, Cl? P 367
LAB: 201

Tuesday:
 
0306BW: To write the formula for an ionic, write the symbol of the positive ion and then the symbol for the negative ion. Add the subscripts that are needed to balance the charges.
If the negative ion is a single element the end of its name changes to –ide Negative polyatomic ion names usually end in –ate or –ite.
0306CW: Do “Apply It!” in your text book on page 368 Do “Assess Your Understanding” on class work paper. Page 368 1a, b, and c.
0306HW: What is the difference between a covalent bond and a molecular bond? P 369

Wednesday:

0307BW: Molecules occur when two or more atoms form a covalent bond and share electrons; a molecular compound is made up of molecules. In some covalent bonds one element pulls more strongly on the negative charge and creates a polar bond.
0307CW: Read pages 369, 370 complete fill-ins. Complete “communicate” from figure 6 on class work paper.
0307HW: Is it possible for a polar molecular bond to be non-polar? Explain. Page 371

Thursday:

0308BW: Not all molecules containing polar bonds are polar overall; sometimes the attractions cancel out, so the molecule is non-polar overall. P 372 The melting point and boiling point of water are much higher than the melting point and boiling point of oxygen. This is because the attraction (slight positive and negative charges) between water molecules requires more energy to overcome than the attractions between non polar oxygen molecules.  
0308CW: Complete 2a, 2b on page 371 and #3 on page 373
0308HW: Prep for Quiz
LAB: as time allows.

Friday:
