Chemistry Recording 12/20 Quantum Electron Configuration
12/20 Chemistry update and homework due 1/10
Hi folks,
Today we spent time on one of the more confusing concepts of chemistry. The confusing concept of the quantum method of electron configuration. This is quite tricky since it is something that is very hard to visualize. Once you do a few, however, it gets fairly simple. Homework this week will be to do quite a few of these configurations.
Homework due 1/10 is to:
Write the quantum electron configurations of
a. Na b. P c. Ar d. Rb e. Ru f. Sb g. Po
Read Chapter 5 pgs. 133 - 152
Answer Review Questions Pg 166 and 167 #'s 13 - 17 and 22 - 37

12/13 chemistry update and homework due 12/20
Hi folks,
Today we went even deeper into the periodic table. We covered the trends of ionization potential and electronegativity. We also spent more time on valence electrons, how atoms bond and Lewis Dot diagrams.
Homework this week is to do the attached .pdf form. It's basically a logic puzzle where you will be putting together the periodic table of elements on and alien planet! Feel free to ask any questions that come up and have fun with this!

Chemical Symbols
Hi folks,
Turns out there's a typo on the chemical symbols I wanted you to memorize. Don't worry about An. It's a typo and doesn't exist. Sorry about that.

12/5 Chemistry update and homework due 12/12
Hi folks,
Today we really dove into the periodic table. We talked about atomic number, atomic mass, size trends of atoms, atomic orbitals and valence electrons. We also introduced diagraming atoms. Next week we will continue working with valence electrons.
HW this week is to:
Read the text book pgs.
57-62
Answer Review Questions #'s 23-32
Answer the following questions
1. How many protons, neutrons and electron 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. Diagram the following atoms. Then tell me how many valence electrons it has, what period it's in, and what group.
a. Magnesium
b. Neon
c. Sodium
d. Chlorine
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, An, Kr, Ag, Sn, Xe, Au, Hg, Pb, Rn
