Key Concepts in Ionic and Metallic Bonding

Delocalized

Electrons that are free to move in metals

Oxidation Number

For a monatomic ion, is equal to the charge

Chemical Bond

The force that holds two atoms together

Polyatomic Ion

A charged particle containing more than one atom

Cation

A positively charged ion

Anion

A negatively charged ion

Electrolyte

An ionic compound whose aqueous solution conducts electricity

Salt

The name for most ionic compounds other than oxides

Electron Sea Model

Represents the way electrons exist in metals

Monatomic Ion

A charged particle containing only one atom

Lattice Energy

The energy needed to separate the ions of an ionic compound

Ionic Bond

The electrostatic force that holds oppositely charged particles together

Alloy

A mixture of elements that has metallic properties

Interstitial Alloy

A mixture formed when small atoms fill holes in a metallic crystal

Oxyanion

A polyatomic ion composed of an element bonded to at least one oxygen atom

Formula Unit

Shows the simplest ratio of ions in an ionic compound

Metallic Bond

The attraction of a metallic cation for delocalized electrons
