Answer:
The charged particles that can be transferred between certain materials when they are rubbed together are electrons.
Step-by-step explanation:
When two materials with different tendencies to attract electrons are rubbed together, one material may have a higher affinity for electrons and pull them away from the other material, resulting in one material becoming positively charged (losing electrons) and the other material becoming negatively charged (gaining electrons). This process is known as triboelectric charging or the triboelectric effect.
