No Class next week (3/29) but there is Class April 5th

Hi folks,

We are going to skip class next Friday for Good Friday but we will have class on April 5th to make up for that snow day we had earlier in the year.  

I apologize if this causes any inconvenience for anyone.

3/22 Chemistry update and Homework due 4/5

Hi folks,

Today we started figuring out quantum electron configuration.  It's quite confusing and strange so we warped a brain or two along the way.  :)

If you want more information on this you may want to take a look at Khan Academy.  

We will be reviewing and working with this more next class so if you just feel plain lost we'll be doing more with it soon.

For homework this week, 

Read your text pgs. 146 - 159.

I also want you to practice doing some configurations.  Do the enclosed worksheet .pdf.

This thing is huge so don't do all of it.  
Do questions:

1-5
11-15
21-36
45
46 a - d
48 a - f

To check your answers, feel free to use this website   Click on the orbitals tab and just scroll over the atoms you're looking for.  Remember, please for your own good grades, check your answers only!!!!

Good Luck!

Chemical Symbol Typo

Hi folks,

Sorry, there's a typo on the list of element I want you guys to memorize.  Ci should be Cl, Chlorine.

Thanks to Greta and Karan for catching that.

Hi folks,

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
Ammonium NH4+
