    If a chemical formula has (O-2)3, does that mean that it is trioxide?

    If two or more elements are in parentheses ( I don’t even know if this is an element, but something like N(SOv3)v2 ), how would you say the name of the two? Are they considered a compound, or two separate elements that just occur in the same number of atoms?

    Nicole: No, it means that it has three peroxide ions, 6 oxygen atoms total.

    Binary acids are two elements..a hydrogen and a halogen. Oxyacids are acids that contain oxygen

    In crossing over, it is okay not to put the charge. Right?
