==Key Stage 4==
===Meaning===
A '''structural diagram''' is a type of [[Chemical Formula|chemical formula]] drawn as a [[diagram]] which shows the arrangement of [[atom]]s in a [[compound]].
===About Structural Diagrams===
: A '''structural diagrams''' gives more detail than a [[Chemical Formula|chemical formula]] about the arrangement of [[atom]]s in a [[compound]] as a [[Chemical Formula|chemical formula]] simply states the number of [[atom]]s of each [[element]] while a '''structural diagram''' displace the locations of [[atom]]s and the [[Chemical Bond|chemical bonds]] holding them together.
