12/16 Chemistry Class and homework due 1/6
Hi folks,
Today we took a look at different types of chemical bonds and how to use that information to name molecules.
For homework,
Read chapter 6 in the text. It starts on page 176.
Also, do the enclosed .pdf. I've included the answer sheet so that you can see if you are on the right track or not.

12/9 Chemistry update and homework due 12/16
Hi folks,
Today we dove a bit deeper into the periodic table and began looking at valence electrons and how they effect the way elements combine with other elements.
Homework for this week is to:
Read Pages 133 - 146 in the text book
Do Review Questions on page 166 and 167 #'s 1- 21. Just do the odd #'s
Create stable molecules using the following atoms.
1. H with Cl
2. Mg and F
3. K with Br
4. Na with Cl
5. H with C
6. C with Cl
7. O and O
8. C and O
9. N and N
10. H and C and N
11. H and C and O

12/2 Chemistry update and homework due 12/9
Hi folks,
Today we took a very quick look the three forms of heat transfer, convection, conduction and radiation. These are how heat moves from one object to another. We also began our investigation into the periodic table and into diagraming atoms. Next week we will get much deeper into these concepts and more.
1. How many protons, neutrons and electrons are in the following atoms
a. Aluminum
b. Antimony
c. Strontium
d. Oxygen
e. A positive ion of Gallium
f. A negative ion of Barium
2. Remember, the atomic weight of an atom is its protons plus its neutrons. With that in mind how many protons and neutrons are in the following atoms. Which ones would be isotopes?
a. Arsenic atomic weight 75
b. Phosphorus atomic weight 27
c. Aluminum atomic weight 29
3. Create a Bohr diagram for the following atoms.
a. Lithium
b. Barium
c. Neon
d. Sodium
e. Argon
f. He
4. Draw the shape of the periodic table and label:
a. Non-metals
b. transition metals
c. halogens
d. Alkali metals
e. Alkali Earth metals
Memorize the following atomic symbols and what they stand for: (Index cards would be great for this!)
H, He, Li, C, N, O, Ne, Na, Mg, Al, Cl, Ar, K, Ca, Fe, Ni, Cu, Kr, Ag, Sn, Xe, Au, Hg, Pb, Rn, P
