periodic table with polyatomic ions and charges

Ionic bonds are electrostatic forces of attraction, that is, the attractive forces experienced between objects of opposite electrical charge (in this case, cations and anions). When electrons are transferred and ions form, ionic bonds result. The nature of the attractive forces that hold atoms or ions together within a compound is the basis for classifying chemical bonding. Unfortunately, the number of oxygen atoms corresponding to a given suffix or prefix is not consistent for example, nitrate is NO 3 − while sulfate is SO 4 2−. For example, perchlorate is ClO 4 −, chlorate is ClO 3 −, chlorite is ClO 2 − and hypochlorite is ClO −. Per- (short for “hyper”) and hypo- (meaning “under”) are prefixes meaning more oxygen atoms than -ate and fewer oxygen atoms than -ite, respectively. Note that there is a system for naming some polyatomic ions -ate and -ite are suffixes designating polyatomic ions containing more or fewer oxygen atoms.

Because you will use them repeatedly, they will all ( Table 1 and Table 2) soon become familiar. At this point in your study of chemistry, you should memorize the names, formulas, and charges of the most common polyatomic ions ( Table 1). Oxyani o ns are polyatomic ions that contain one or more oxygen atoms.

These ions, which act as discrete units, are electrically charged molecules (a group of bonded atoms with an overall charge). The ions that we have discussed so far are called monatomic ions, that is, they are ions formed from only one atom. | Key Concepts and Summary | Glossary | End of Section Exercises | Polyatomic Ions Write formulas for ionic and common covalent compounds.
