Materials are often listed in order of the polarity of charge
separation when they are touched with another object. A material
towards the bottom of the series, when touched to a material near the
top of the series, will attain a more negative charge, and vice versa.
The further away two materials are from each other on the series, the
greater the charge transferred. Materials near to each other on the
series may not exchange any charge, or may exchange the opposite of
what is implied by the list. This depends more on the presence of
rubbing, the presence of contaminants or oxides,
or upon properties other than on the type of material. Lists vary
somewhat as to the exact order of some materials, since the charge also
varies for nearby materials.
