Using ion in names

Postby Alyssa Pelak 1J » Mon Dec 04, 2017 3:03 pm

When do we need to add the word ion to the end of the coordination complex name? Is it just when it has a + or - charge, or is it all the time?

Thank you!

Yes, I believe if it just asks you to name the compound and there is no charge, you don't need to write "ion." If it's a complex ion (aka has a + or - charge), you'll need to write ion at the end of the name.

Dear student,

Only if you write the formula you have to have to right the ion name, because it matters if it is on the formula, it will determine how you name it. For example: [Fe(NH3)Cl4]- where the name would be diammine dichloro ferrate(III) where the ion name is not there in the name but it is present in the formula.

Hope this helps
