Isotopes, Atomic Mass, Brief Atomic History

Below you will find notes, Objective Practice problems, and isotopes/atomic mass practice problems. The practice problems are not due for a grade, however it is recommended that you use them to study for your quizzes.

REMINDER: Quiz 2.1 NEXT CLASS [09.23 - 09.24] (objectives 1-3 on practice problems)

Items that have already been due this unit: Aluminum Lab (09.21 - 09.22), Candium Lab (09.21 - 09.22), Scientist "mini-book" (09.21 - 09.22)

Scientist Notes: Supplemental

Objective Practice Problems

Isotopes and Average Atomic Mass Practice

Look below for atomic models as well...

Atomic History and Atoms Basics

BY NEXT CLASS...create a mini-book about the four scientists you discussed with your group in class today.  Fold a piece of printer paper in half to create four pages, and each page should have one of the scientists on it.  The following information should be included for each.

• experiment name (if applicable)
• experiment diagram (labeled)
• list of observations made and interpretation of each
• resulting atomic model (if applicable)
• resulting particle or particle property (if applicable)

We will be doing a small lab activity next class followed by a small assessment over the material we have been discussing in class the last couple of days (not the scientists yet).  We will be discussing electrons in greater detail over the next week, so be ready!

Aluminum Lab and Additional Conversion Practice

Below is the aluminum lab and a few hints to get this done if you haven't already. It is due by Friday (09/18).

Hint #1
Volume = l x w x t (t is thickness)

Hint #2
D = density = m / v

Hint #3
You are basically finding me how many aluminum atom "bricks" it takes to build a wall of aluminum atoms as thick as the aluminum foil...

ADDITIONAL CONVERSION PRACTICE
Below is the link to the additional conversion practice.  Remember this is optional unless you were told differently in class.  Those that were directed to complete it, it is due by 09/24 at the latest.

Additional Conversion Practice

Dimensional Analysis

We have been doing dimensional analysis with various types of conversions the last week or so.  Below you will find some notes concerning this topic as well as some other instructional aides (videos, practice quiz, etc) for use with this unit.
