Next Honors Chem Exam- updated
the first test of the second quarter...let's start strong...written-response format...next Monday AND Tuesday (total of two periods to complete the exam). Test will cover material (all notes and homework) from the Wave-Mechanical (Quantum) Model of the Atom through the Periodic Trends covered this week...test will likely be worth 150 total points...practice your written explanations and drawings...
update: the test covers material up to and including the explanations of periodic trends (across any period from left to right and also down any group); we covered six trends or explanations ending with the periodic trend in electronegativity. The worksheets that I uploaded on Friday will provide additional practice for this test (you can ignore the questions on "dot structures" and types of compounds formed).
Remember, you will need to APPLY/EXPLAIN the EFFECT of the effective nuclear charge and also the EFFECT of the number of OCCUPIED principal energy levels ON whatever is asked in the question. If you merely state that a given trend is due to, say, high Zeff and a low number of principal energy levels, you will receive little to no credit.
TIP: Start off by writing a key in the upper left corner of your first page:
Zeff = effective nuclear charge
OPELs = occupied principal energy levels
You may not abbreviate ordinary words; your test is not a chatroom. Do not say that "NRG" is energy (unbelievable that some did that on the last exam).
Also, carefully read and practice the words in our spelling list ; we're in the second quarter so spelling and grammar should be excellent by now. Again, I suggest that you avoid pronouns in your written explanations unless you are absolutely sure that you are using the pronouns properly and unambiguously.
The exam will be given on Monday but a few questions will not be seen until Tuesday; I will return Monday's work to you to start the exam on Tuesday so don't worry about finishing all of your answers on Monday. Just put each answer on a separate page if you want to skip around.
Looking forward to a strong WRITTEN start to this quarter.
Good luck on Monday and Tuesday!
