The correct answer is: Rubbing the balloon along her hair moves electrons from her hair to the balloon.
To understand why the hair becomes attracted to the balloon, we need to understand the concept of static electricity. When two objects come into contact and then separate, electrons can be transferred from one object to the other. In this case, when Isabella rubs the balloon against her hair, friction between the two surfaces causes electrons to be moved from her hair to the balloon.
Electrons are negatively charged particles, so when they move from the hair to the balloon, the balloon ends up with an excess of negative charge, while the hair ends up with a deficiency of electrons, resulting in a positive charge.
Opposite charges attract each other, so the positively charged hair is attracted to the negatively charged balloon. This is known as electrostatic attraction.
It's important to note that protons, which are positively charged particles found in the nucleus of an atom, are not involved in this process. It is the movement of electrons that creates the charge imbalance and leads to the attraction between the hair and the balloon.
