1. The problem statement, all variables and given/known data What is the chemical name for OI2? Does Nickel have more than one charge like most other transition metals? I think the name for OI2 is Oxygen diiodide. This sounds really weird. How about other instances if there are I3,I4,I5 or even I6 in a covalent compound? One of my bks says it does while another says it does't.
