(PO 4)3–, is an example of a polyatomic ion (Figure 2). A polyatomic ion is an ion that consists of a stable group of several atoms acting together as a single charged particle. ˚ e ionic charge of a polyatomic ion is shared over the entire ion rather than being on just one atom.

PO 3. Q. What is the correct name for this polyatomic ion: PO 4 3–.

Although most polyatomic ions are pussies, (all electrons are paired), some are radicals. I think this could be cleaned up a bit.

Select the name of the ion for information about its occurrence, uses, properties, and structure. Blank entries are uncommon or unstable; for a complete table see the Field Guide to Polyatomic Ions. A rule or two about polyatomic ions From –ate…adding an oxygen makes per- -ate…taking away an oxygen (from the original –ate) makes –ite…taking away another oxygen makes hypo- -ite… An example: Hypochlorite ClO-1 Chlorite ClO2-1 Base ion → Chlorate ClO3-1 Perchlorate ClO4-1 2020-04-18 · Polyatomic ions are ions which consist of more than one atom. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.

The phosphate ion has a charge of −3. The formula of the phosphate ion is PO 43−. The phosphate ion can form compounds with positive ions such as the sodium ion or the calcium ion.

Table of Polyatomic Ions There are a number of ions that are not individual atoms but are composed of multiple atoms that are covalently bonded together. However, this group of atoms is most stable when it has either lost of gained an electron and thus existed as a charged ion.
