Today, in Chemistry 163 Period 5, we began class by getting our previous homework checked (pages 18 and 19, a.k.a. Molecular Shapes 2&3) and stamped. Mrs. M asked us if we needed explanation on anything, and we did a few examples from the pages. (For answers, please refer to the photos...sorry if quality is bad. Remember: you do have the VSEPR sheet to refer to for more answers!)

page 19: After that, we continued on to our next activity: Molecular
Geometry - the three-dimensional arrangement of the atoms that constitute a molecule. We used the packet that consisted of rows of molecules and columns of the Lewis Structure, # of Atoms on central (refer to the gold VSEPR sheet for the #/#/# answers), # of Lone pairs, Shape, 3D Picture, and Stamp (from Mrs. M).
ex.
We used wooden spheres, sticks, and springs to create 3D molecules during class. If you did not finish or get them all checked, please finish the work tonight for homework, and we will have time in class tomorrow to finish creating them. Enjoy the late arrival tomorrow! But do your homework!
HOMEWORK:
- finish Molecular Geometry packet
- ^remember to answer the questions on the 2nd page!
- ENJOY THE LATE ARRIVAL
