Today we discussed some of the trends on the periodic table. Electronegativity, Radius, Ionization Energy, and Metallic Nature.
We also covered the methods atoms can bond to one another, covalent, metallic and ionic.
Homework for this week is to:
Read 173 - 186
Do questions starting on pg 200
Odd #'s 1 - 23
Memorize the following chemical symbols and the elements they represent. I highly recommend making flash cards for this.
H He Li C N O NA Mg Al S Cl K Ca Fe Ci Zn Si Au Sn Hg Pb
These are common polyatomic ions. Memorize these and their charges.
-1 Charge
Hydrogen Sulfite HSO3-
Hydrogen Sulfate HSO4-
Nitrite NO2-
Nitrate NO3-
Hydroxide OH-
-2 Charge
Sulfite SO32-
Sulfate SO42-
Carbonate CO32-
+1 Charge
