Understand the definitions of the given terms: Ionization, Condensation, Polymerization, and Sublimation.
Ionization is the process where an atom or molecule gains or loses electrons, resulting in the formation of positive and negative ions.
Condensation refers to the phase change from gas to liquid, not involving ion formation.
Polymerization is the chemical process where small molecules (monomers) join to form a large molecule (polymer), without necessarily forming ions.
Sublimation is the phase change from solid directly to gas, also not involving ion formation.
