Hint for Naming NiI Ni is a transition metal and Iodine is a non-metal. This is an ionic compound.
- Name the metal as it appears on the Periodic Table.
- Name the non-metal (Iodine) by replacing the ine with ide.
- Look at the chemical formula to find the charge for Ni. Since I has an ionic charge of -1, and we have One I atom, Ni will have to have a charge of +1. To show that we write the Roman Numeral one, like this (I), after the name for Ni.
Don't get the I for Iodine confused with the Roman Numeral (I)!
