Two monomers are joined to make a dimer.
Every halogen can form their molecules by a single covalent bond.
Only halogens and members of the oxygen group can form diatomic molecules joined by a single covalent bond.
Molecule
They create molecules. If the atoms joined together are from different elements they create polar molecules.
Solid AlCl3 is ionic. Liquid and gaseous AlCl3 is present as a covalent dimer, Al2Cl6. At high temperatures the dimer dissociates to form the planar covalent monomer AlCl3.

Dehydration reactions
A monomer is a fairly simple molecule that can be joined by covalent bonds to form larger molecules called polymers. Two monomers constitute a dimer. Three constitute a trimer. And, beyond that, it is just called a polymer.
Monomers are small hydrocarbon molecules that form polymers.
Two monomers to a dimer - this is a condensation reaction that involves the combining of -OH from the [enzymatically specific] one and the +H from the other to form H2O.
Every halogen can form their molecules by a single covalent bond.
The opposite sequence, so the two strands can bind together to form a dimer.
nitrogen can :)
