Chemistry Ionic Compounds Polyatomic Ions ~ When a polyatomic ion forms an ionic bond with another ion a polyatomic ionic compound is made. For example the 1 barium ion can form an ionic bond with the 1 hydroxide ion to form the barium hydroxide baoh ionic compound. But the polyatomic ion will behave as a single unit. Remember because it is a cation when it reacts and forms a compound it is cited first in the chemical formula. Ionic compounds containing polyatomic ions. Compounds formed from such a combination of ions are polyatomic ionic compounds. A special type of ionic compound is exemplified by ammonium nitrate nh 4 no 3 which contains two polyatomic ions nh 4 and no 3 as the name suggests a polyatomic ion is a charged entity composed of several atoms bound together. The polyatomic ion forms ionic bonds with other ions and acts externally as a unit just like monatomic ions. When polyatomic ions are included the number of ionic compounds increases significantly. Ammonium nh 4. Indeed recently is being sought by users around us, perhaps one of you. People are now accustomed to using the net in gadgets to see video and image data for inspiration, and according to the title of this post I will talk about about Chemistry Ionic Compounds Polyatomic Ions. Learn vocabulary terms and more with flashcards games and other study tools. Ionic compounds containing polyatomic ions. The resulting polyatomic ionic compounds can take part in the different types of chemical reactions dissolving and dissociating in water. Remember because it is a cation when it reacts and forms a compound it is cited first in the chemical formula. A special type of ionic compound is exemplified by ammonium nitrate nh 4 no 3 which contains two polyatomic ions nh 4 and no 3 as the name suggests a polyatomic ion is a charged entity composed of several atoms bound together. Polyatomic ions with a positive 1 charge do occur but the main one you ll encounter and need to know is the ammonium ion. Nh and no 3. Except when there is more than one polyatomic ion then its formula is written inside. Well known examples are sodium hydroxide naoh with oh as the polyatomic anion calcium carbonate caco 3 and ammonium nitrate nh 4 no 3 which contains two polyatomic ions. This is the structure of an ammonium ion.
Polyatomic ions are formed when a group of atoms have a charge.

Remember because it is a cation when it reacts and forms a compound it is cited first in the chemical formula. In addition polyatomic ions and those ionic compounds take part in chemical reactions such as acid base precipitation and displacement similar to monatomic metallic ions.
