Covalent bonding requires at least one electron from each atom
Unsaturated carbon compounds are created when carbon forms double or triple bonds with itself
Saturated carbon compounds are those where carbon forms single or no bonds with itself
Bonding electrons are those that are shared between atoms
Non-bonding electrons are those on the outer shell not shared by the atoms
Non-bonding electrons form lone pairs
An electron dot diagram shows the electrons in the outer shell with the bonding electrons facing each other
The structural formula of a molecule uses a line to represent a pair of bonding electrons and represents the shape of the molecule
An isomer is a compound with the same molecular formula arranged in a different structure from standard molecules
Hydrocarbons are simple organic compounds containing only hydrogen and carbon
