Ionic bondings
« on: October 25, 2015, 11:03:58 AM »
Hi!
I was wondering if an ionic bonding MUST contain a metal and a nonmetal ion or it just has to be a cation and an anion. If it must contain both then what about ammonium nitrate. I have been searching for a long time but i can't find consistent answers.
Thanks all!

No, ionic bonding is certainly not limited to only metals with non metals. I think the term you should be looking for is "polyatomic ion."
Ammonium nitrate, as you say is one example of many polyatomic ions.

Please take note! Every ionic compound is between a cation and an anion. However -- ignoring polyatomic ions, all ionic compounds are between a metal and a nonmetal. If it is a bond between a nonmetal and a nonmetal, and neither are polyatomic ions, it is a covalent bond. Hope this helps!
