Unit 2 

Properties of Matter

In Unit two we begin looking at the atom, and the periodic table.  We'll look at the history of atomic theory, atomic structure, and nuclear chemistry.

​On the first day of unit two we review the physical and chemical properties of matter.  Much of this was covered in unit 1, so we likely also covered the history found in unit 2.2
Unit 2.1 Note Questions



The first half of this video goes over the history of the atomic model and the periodic table.  As this can be a bit dry in class i elaborate much of these stories, however this video does go over key points which you need to know.  Also the beginning of the video could have been covered on the first day of this unit.











​
We also watched this video about the duality of matter, that electrons exist as both a wave and a particle.
Unit 2.2 Note Questions


We continued our dive into the periodic table of elements by tackling average atomic mass.  The primary objective for this lesson is that you be able to calculate the average atomic mass of an element from its percent abundance and mass.  However, as an added point we did discuss calculating the percent abundance from known average atomic masses.  
Unit 2.3 Note Questions
We cement the idea of average atomic mass by conducting the "Beanium lab." 
After the lab we took our unit 2 quiz:
-write the isotope notation for an element
-determine the number of protons, neutrons, and electrons for that element
-assign the element to a family/group
-calculate the elements average atomic mass





​Our final sub-unit was about nuclear reactions, and half life.  Be sure to know the three types of radiation and be able to predict nuclear reaction products.

Unit 2.4 Note Questions
Then we finished unit 2, make sure you've completed the unit 2 homework!
