Wednes-Day 2
Bio- we finished our unit review; review your notes, watch all posted Blackboard animations, and keep writing all of the relevant information that you will transfer directly from your short-term memory to your test paper as soon as the test begins. This way, you will have your own handy reference sheet for the test to make you faster and more accurate.
Since proper scientific method and graphing skills are always tested, review your notes, text, and past tests on those skills.
Good luck tomorrow! I'll be in Room 301 around 8AM. Beware, there is also a Chemistry exam tomorrow so you need to be prepared with specific questions from your studies.
Chem 7/8- we discussed salts of transition metals, noting that most transition metals CAN form more than one type of cation. Using the KNOWN nonmetal anion charge in a given formula, you can always deduce the charge on the transition metal cation that balances the negative charge from the anion(s).
We then looked at the electron configurations of the various cations of a given transition metal.
Remember, salts of transition metals form COLORED solutions; salts of representative metals e.g. NaCl form COLORLESS solutions.
ALL solutions are "clear"/transparent, whether or not they are colored.
We then did a comprehensive activity using the Reference Tables to see the periodic trends. Check your work on that, study, and good luck tomorrow!

Chem 9- we discussed salts of transition metals, noting that most transition metals CAN form more than one type of cation. Using the KNOWN nonmetal anion charge in a given formula, you can always deduce the charge on the transition metal cation that balances the negative charge from the anion(s).

Check your work on the comprehensive Reference Table/Periodic trends worksheet that is posted on Blackboard, study, and good luck tomorrow!
