Sections 2H & 5: Graph and study!

Your graph:

  • The x-axis should be 'Atomic Number'. Recognize that we now know that the rows of our cards today are rows 2-5 on our periodic table (NOT including the d block!). So you can assign each card an atomic number! 
  • The y-axis you can choose. You can either have it be the electronegativity (the bottom left #) OR the number at the top left (try to figure out what that is, based on the trend, so that you can label the axis). Whatever you choose, just stick to it! You have to be consistent across all cards. 
  • Make sure to plot the 'Missing Element'. Based on the trends you see, try to best predict the missing plot point - be sure to label it. 
  • Look over your graph, does it make sense? If you can see all the different trends we've talked about on the card and predict which number corresponds to which trend, you'll be set for the quiz! 
If you want to study with me tomorrow: 
Tomorrow during CP I have my department meeting. However, I am available during both lunch periods. Stop by my office, if you have questions!

  • light being described as a quanta, rather than a purely as a wave (why this is important)
  • absorption and emission spectra and how they relate to energy levels in an atom
  • wave-particle duality of an electron (specifically that they act like standing waves....how that relates to energy levels)
  • 4 quantum numbers 
  • principles (Aufbau, Pauli, Hund) 
  • electron configurations (short and long form)

All: Complete your lab packet. For extra credit:
You can create the graph from the back page of the lab digitally (on excel, logger pro, etc). Once you've plotted all your points, use the curve fit option 'natural exponent'. You may need to mess around with some of the line fitting options to get the best fit. Once you've done that, trace the curve and mark the point that best expresses the half-life of our sugar cubes. A box should pop up that represents all the info from that data point - make sure that's included on your graph. Print the graph and the data set and attach it to your lab.

http://phet.colorado.edu/en/simulation/rutherford-scattering

There are two tabs (Rutherford and Plum Pudding), as well as several settings (energy, number of protons, etc). For each tab you will play around with the settings and make some observations. Remember that you can only draw accurate conclusions if you change only one variable at a time. For each tab, fill out a chart in your notebook that looks like this (you should have at least 3 rows of observations for each):


Variable changed
Observation
Possible explanation of the result










Section 5: On Monday, you will 'adopt an element'. You will begin a project on one element from the periodic table. Your homework for tonight is to start doing some light research. Look up some information about elements that interest you from the periodic table (where they're found in nature, what they're used for, etc) and email me you top 3 choices in order. Consider choosing a less known/common element!

Section 3H: Today in class we did an activity where we saw TRANSMUTATION (cool word, right?). This is where one element or isotope transforms into another by releasing or gaining a decay particle. In our case, we only saw particle emission (an element becoming another element by releasing an alpha or beta particle - and energy! Don't forget E=mc^2!)

In your homework worksheet you will do more practice with these two types of emission and you will also see positron emission and electron capture. In electron capture, you have the decay particle on the reactant side, rather than the products side.
I've done the first problem in each section to get you started.

Also, so that you can practice all types of nuclear decay reactions, do these in your notebook:

The worksheet that goes along with the sim can be found under Homework Docs. YOU ONLY NEED TO COMPLETE THE FIRST TWO PAGES. Start by just messing around with the sim so you can see how it works. Make sure to look at the information provided about the amount of salt and water on the right hand side. You will need to use the tabs at the top for the second page of the worksheet. Be sure the READ DIRECTIONS carefully throughout the worksheet!
NOTE: If you don't get the Pre-Lab Vocabulary definitions from the textbook first, you will have a lot of trouble completing the worksheet!

Students going on Montserrat: On Thursday we will look at a Phase Diagram. There are two videos on the phase diagrams below, and a great explanation in your textbook on page 347. The videos have the same content - I just put two because they are different styles of video - you only need to watch one (you can watch both if you'd like).
Practice reading a Phase Diagram in the worksheets under Homework Docs. If you feel lost on any of the 3 graphs you've seen, please make an appointment to see me.

All: The Limiting Reagent worksheet (and answer key!) can be found under 'Homework Docs'; FYI many of you already received this worksheet in class. Here is a GREAT video to help you with this worksheet:
Limiting Reagents

Note: you will see some 'fancy' words on this worksheet like "theoretical yield" and "actual yield", don't worry - you're fancy enough to understand them!
The root word in theoretical is theory. Meaning, in theory, if I have 100,000 hot dog buns, how many hot dogs could I sell? Obviously, as we discussed, the answer is 100,000. BUT, if I only order 10,000 hot dogs than my actual yield would be 10,000. In one case (theoretical) we don't factor in limiting reagent, we just do our normal stoichiometry, but in the other (actual) we do! In actual yield we look for the reactant that made the least product and viola! we know how much we can actually make.


Study your stoich for Friday!! :)

February 3 - 6

All: On Thursday, you will be asked to calculate the number of atoms in your name, as we discussed in class. You should arrive on time for lab, and you will complete and hand-in your lab to your proctor.
If, for some reason your class is canceled, you MUST pick up a lab from the HMO and complete it in your free time (find some chalk in an empty classroom, ask a science teacher for a scale - you can do this, I believe in you!).  Completed labs should be placed in my mailbox or returned to the HMO.

I recommend, if you complete your lab quickly on Thursday, that you stay until then end of 50 minutes and study stoichiometry with your peers.

 By next class please have all of the following complete:

  • Any previously assigned homework worksheet
  • Complete the 'Formula of a Hydrate' lab
  • Watch and take notes on this video:
  • Be prepared to do the following types of conversions
    • Gram to gram
    • Gram to mole
    • Mole to gram
    • Gram to Molecule 
*If you missed today's lab, be sure to pick up a lab manual from me tomorrow before lunch!
