Matter with only one particular kind of atom is known as an element. These atoms can either be located individually or combined into larger units. An example of this would be the notion that carbon is an element, because at it's pure substance state it's composed of only carbon atoms.
Diatomic or Diatomic Molecule- meaning containing only two atoms.
As a molecule containing 2 atoms IBr can only be linear.
A chain hydrocarbon has a long molecule containing only carbon and hydrogen.
An elemental molecule, like H2 or O2.
