snow day?

could be tomorrow ...on a day 4 no less....I keep running into details about per tab that I should talk about after the fact...will have to compile and post as supplements and alert the class...
on the REgents tables, they will have un dos tres quad etc for naming of the heaviest elements...
e.g. F2 etches glass
forms the only weak halogen acid
Bromine is NEVER purple...it is always reddish brown...

returning the Tday assignments...no two people got the empirical formula for the CHNBrO compound...change those numbers...they aren't precise enough....
