Today we started out class normally as we always do by checking the previous nights blog and doing attendance.

After that we opened up page 11 and we finished it. Mr. Henderson told us not to forget the Greek prefixes, and that two was di not bi as normally used. Also, 8-octa, 9-

nona, and 10-deca. He also recommended we use the PT to help us finish the page. A oddball thing I noticed was that

when doing 4 atoms of oxygen instead of doing tetraoxide as most people would think, its actually teroxide.

After page 11 we started on page 12, which we didn't finish but we got a good start on. on this

page we were figuring out if the compounds were molecular or ionic. Ionic compounds are formed by nonmetals and metals forming and they also DO NOT use Greek prefixes. Molecular compounds are made by 2 nonmetals and there can only be 2 elements. Don't forget to put

the roman numerals if transition metals are used!

After page 12 Mr. Henderson introduced how to write names for acids and gave us some notes which are pictured on the left. We then started doing page 13. Mr. Henderson told us that almost all the acids we were going to talk about were going to have a formula that started with H. if u need extra help on naming acids all the rules are on page 43 in our chemistry books.

After learning about acids, Mr.Henderson told us to turn in our lab notebooks and we headed off to the computer lab to work on anything we had in mind. Then Mr.Henderson reminded us to work on our webassigns and that there is going to be a popquiz on monday!
