Definitions:

Electrons

Subatomic particles with a negative electrical charge, found in orbitals surrounding an atom's nucleus, and participating in chemical bonding and conductivity.

Alternating Copolymer

A copolymer where two different monomers are linked in an alternating sequence, offering unique properties compared to random or block copolymers.

Addition Polymer

This type of polymer is formed by the addition reaction between monomers with double or triple bonds, leading to a long chain molecule without the elimination of small molecules such as water.

Condensation Polymer

A type of polymer formed by the reaction of monomer units with the loss of a small molecule, such as water, leading to the formation of a longer chain.
