Final answer:
When rubbing two neutral objects together, electrons are transferred between them, causing one object to become negatively charged and the other positively charged.
Step-by-step explanation:
When you rub two neutral objects together to charge them, electrons are transferred. In the context of neutral objects, neutrons and protons remain within the atomic nuclei and do not transfer during this process. Unlike these subatomic particles, electrons are located in the electron cloud around the nucleus and are more easily dislodged and transferred through contact and friction.
As such, one object will gain electrons and become negatively charged, while the other loses electrons and ends up with a positive charge due to the deficit. The absolute value of the charges on both objects will be equal, ensuring the law of conservation of charge is upheld.
