Bohr Model Activity

In class today, we worked on creating models of various elements and then answered questions about the models.  This was intended to be a review of Bohr models as well as reinforcing concepts already learned in preparation for the test on Thursday.  The worksheet we worked on is below.

Review/Catch Up Day

In class today, we finished up our Element Trading Cards and worked on the worksheet below.  This worksheet is REVIEW.  You should have a pretty good handle on identifying mass, atomic #, protons, neutrons and electrons at this point.  We have a test on Thursday!  I have included a review sheet below for you to begin studying for the test if you choose.  The Element Trading Card is due tomorrow or it's considered LATE.  Late, will lose 10% of their overall grade for the assignment.

Day 2 in the computer lab.  Today we worked on creating a trading card for an element.  The following links will help you see what the finished product should look like as well as a rubric so you know how you will be scored on your card.

Use the following links in order to complete the worksheet that was passed out in class today.  If you missed class, or just need another copy of the assignment, click here.

Interactive Periodic Table websites (to get more  information about each element, just click on that element in the table).
Also, you must identify why the following elements have their symbols.  Potassium=K  Iron=Fe
Gold=Au   Silver=Ag    Lead=Pb    Mercury=Hg     Antimony=Sb    Sodium=Na    Tin=Sn   Tungsten=W

Bohr Model Day 2

In class today we reviewed the Bohr Model activity by completing a worksheet that had a table and 18 Bohr models for students to complete.  This was done in class but if not finished, it becomes homework.  If you are having trouble, please look back at previous posts and/or search the internet.

 Bohr models are the typical drawings of atoms where the nucleus contains protons and neutrons that are encircled by electrons.

          

Using the periodic table, you can determine the number of protons, neutrons, and electrons.  Here is a quick review:

Atomic Number = number of protons
Atomic Mass - Atomic Number = number of  neutrons
Atomic Number = number of electrons

Bohr Model Activity

Today we created Bohr models using tennis balls, golf balls and students.  Bohr models are used in order to model different elements.  We practiced making the elements at least Hydrogen through Boron as well as some ions and isotopes as well.  From the activity, I wanted students to see the correlation between the Group # and the # of valence electrons as well as the Period # equal to the number of shells the element had.  Once done with this activity, we had a worksheet that just reinforces using the periodic table.  Tomorrow we will have a paper to review what we did with Bohr models.

Ions and Isotopes...Oh My!

Can you guess from the title of this post what we did in class today?  We learned about ions and isotopes!  We viewed the Brainpop videos for each topic, then completed a "cheat sheet" to help us remember the differences between them.  Lastly, we had a worksheet to complete over the topic.  All of the links are below.
