==Key Stage 4==
===Meaning===
A '''double bond''' is a [[Chemical Bond|chemical bond]] in which two [[electron]]s are shared or transferred from the [[Outer Shell|outer shell]] between two [[atom]]s.

===About Double Bonds===
: In [[Covalent Bond|covalent bonds]] a '''double bond''' means two [[electron]]s from the [[Outer Shell|outer shell]] of an [[atom]] are shared with another [[atom]].
: In [[Ionic Bond|ionic bonds]] a '''double bond''' means one of the [[element]]s has gained or lost two [[electron]]s from/to one other [[element]].
