"per _____ ate" 1 more oxygen
"-ate" "normal" # of oxygen
"-ite" 1 oxygen less
"hypo _____ ite" 2 oxygen less
(+) and (-) ions attract to form neutral compounds.
(Na)1+ (F)1- ---> NaF
(Na)1+ (O)2- ---> Na2O
(Mg)2+ (Br)1- ---> MgBr2

Nov 20, 23,24, Dec 15-18, 2020
We will not meet on these days as a class.
I want you to go the the AP Chem Board site and watch videos and work on practice problems for review of topics for the semester.
