Matter is neutral. It is composed of an equal member of positive and negative charges. Some materials tend to attract a stronger negative charge than others. Electrostatic series:
Electrostatic series: In reality this is what we will be seeing: 1. Rubber 5. Silk 2. Ebonite 8. Acetate 6. Wool 3. Polyethylene 7. glass 4. Cotton 9. Cat’s fur
Rubber Ebonite Polyethylene Cotton Silk Wool Glass Acetate Cat’s fur So, elements at the top of the list tend to acquire negative charges when rubbed with materials lower down in the list.
