==Key Stage 4==
===Meaning===
An '''ionic bond''' is a type of [[Chemical Bond|chemical bond]] in which [[atom]]s form [[ion]]s be exchanging [[electron]]s.

===About Ionic Bonds===
: [[Atom]]s are more [[Chemically Stable|chemically stable]] when their [[Outer Shell|outer shell]] is full of [[electron]]s. One way [[atom]]s can have a full [[Outer Shell|outer shell]] is either giving away an [[electron]] or gaining an [[electron]] from another [[atom]].
: When an [[electron]] has been transferred from one [[atom]] to another the [[atom]]s become [[charge]]d and form [[ion]]s. These [[ion]]s experience an [[Electrostatic Force|electrostatic force]] of [[attraction]]. This is known as an '''ionic bond'''.
: '''Ionic bonds''' usually happen between a [[metal]] and a [[non-metal]] [[element]] when a [[metal]] [[atom]] loses one or more [[electron]]s and the [[non-metal]] [[atom]] gains one or more [[electron]]s.
: '''Ionic bonds''' can be represented by a [[Dot and Cross Diagram]] to show how the [[electron]]s are transferred from one [[atom]] to another.
