Chemistry 11:  We began by adding notes to our graphs for Lab 11A.  It is important that chemists know the trends in the radii of atoms and ions in order to understand patterns in melting point, bond strength, and other properties of compounds and elements.  We read pgs 171 - 176 and completed Unit 8 # 57-67.  We continued on with our Dead Sea lab.  The Lewis Dot Structures were checked today too.
