This activity tests your observation 
and reasoning skills
and your ability to draw conclusions
from the physical evidence present.

9/30 - 10/09      

FIRST MIDTERM 10/01

Presentation video:

1. Elements in the periodic table   8 min.  L. Lee

2. Isotopes  9 min.  L. Lee

Readings:

1. Looking for Patterns- The Periodic Law and the Periodic Table   11 min.  Chemistry LibreTexts

2. Elements - Defined by their numbers  7 min. Chemistry LibreTexts

Interactive:

How are elements different from one another? 

When you click the missing element, 
it shows up on the upper left corner 
with its atomic number and mass 
number. Use the slider for the protons, 
electrons and neutrons at the bottom 
of the screen to build a neutral atom.
 Add the correct number of protons, 
electrons and neutrons to create the 
correct atomic structure for that 
element. Take a screen shot to show 
me  the element you recreated.

Do the Periodic Table game in 
this week's folder
                                      DUE 10/09

A short, simple matching game. In the 
spaces, put the number of the definition 
for the word. 
In the end, the numbers in each row and 
column should add up to the same number.

10/07 - 10/16  

Readings: 

1. The properties of protons, neutrons and electrons  7 min.  Chemistry LibreTexts

2. Ions - losing and gaining electrons  6 min.  Chemistry LibreTexts

3. What are ionic compounds?    6 min.   Chemicool Dictionary

4. What is a covalent bond in chemistry?  5 min.  Anne Marie Helmenstine

Video:

1. Ionic bonding introduction    7 min.  Tyler DeWitt

2. Chemical bonding   5.5 min.   Creative Learning

Interactive:

Build an atom   

Select "Build an atom". Click the 
+ sign on"Element", "Net Charge" 
and "Mass Number" on the right. 
Check the boxes for "Element", 
"Neutral/Ion" and "Stable/Unstable". 
This displays the element name
and specifies you're building a 
neutral (no charge) and stable atom. 
Look at a periodic table. Build a lithium 
atom by dragging in how many protons
 first? Balance this with how many 
electrons? Check the atomic mass to
 see how many neutrons are needed. 
Play around building other atoms. Take 
a screenshot of an atom you've
 built (not Li) and email it to me.
