Please make models of three molecules / ion listed below with paper, sticks and tape:
BF3, NH3 and (NH4)+
Step 1, write electron configuration of the center atom
Step 2, write Lewis structure of the molecule (i.e. indicate valence electrons with dots around the center atom and terminal atoms)
Step 3, determine polarity of each bond
Step 3, determine the 3-D geometry of electron domain of the molecule
Step 4, determine the geometry of 3-D geometry of the molecule
Step 5, make model of the molecule with paper, sticks and tape
Step 6, indicate the position of each atom on the model (write on)
Step 7, determine if the molecule is polar or non-polar
We will meet in the classroom at 2:00 PM to summarize this school year’s 9th grade Chinese study and the recent final test.
After that, we will to go to the field outside of the building to have fun. I will bring drinks, fruits and healthy snacks, as well as utensils, cups, plates and napkins. Parents are welcome to join us.
Majority students of this class will take Physics / AP Physics next school year ( survey result at our 06/11 class). In the class meet on 06/18, I will teach contents of interface of high school Physics and Chemistry, including Wave Properties of Matter, Atomic Spectra, etc.
