Hon Chemistry 2-4-09 Binary Molecular Compounds
HON CHEMISTRY: Aaaaaahhh, these short periods are killing me! Here’s the lecture from Wednesday on writing and naming binary molecular compounds. First though, we went over homework – Pay attention to the details on this whole nomenclature and writing formula business. It will pay off in the end!
BTW: Here’s a copy of the chemical formula worksheet, if you didn’t get a copy of it today – click on the title to open: Chemical Formulas WS I

Aniah: Sorry about the confusion – because we got a day behind, there wasn’t any homework for regular chem. except for reviewing the symbols of the elements. The homework you heard was for honors. I hope I didn’t say it for the wrong class! Of course, if you want to work ahead…
Monday we’re going to the computer lab to finish the 3D molecule presentations. If you want to download jing at home though, go to jingproject.com.

This isn’t my question; Is it just the answers that are highlighted in gray? I thought it was just yours but Tim’s is too.

On our homework there is a problem that says name this binary compound according to the stock system. If it is SO4 would you name it sulfur tetraoxide or sulfur tetroxide?

Can binary molecules become polyatomic ions or are those a completely different field?

why are all the elements that end in ide always last in the formula?
