==Key Stage 4==
===Meaning===
'''Simple covalent molecules''' are small [[molecule]]s in which the [[atom]]s are held together by [[Covalent Bond|covalent bonds]].

===About Simple Covalent Molecules===
: '''Simple covalent molecules''' are simple in that they have only a small number of [[atom]]s.
: '''Simple covalent molecules''' can be [[element]]s or [[compound]]s.
: The [[Physical Property|physical properties]] of [[substance]]s made of '''simple covalent molecules''' such as [[Boiling Point|boiling point]] and [[Melting Point|melting point]] are determined by the [[Intermolecular Bond|intermolecular bonds]].
: [[Substance]]s made of '''simple covalent molecules''' are usually poor [[Electrical Conductor|electrical conductors]] and poor [[Thermal Conductor|thermal conductors]].
: The [[Covalent Bond|covalent bonds]] in a '''simple covalent molecule''' can be represented with a [[Dot and Cross Diagram]].
