Question

When you walk across a carpet, you become negatively charged. Why do you receive a shock when you touch a metal door handle? Electrons jump from you to the handle Protons jump from you to the handle Electrons jump from the handle to you Protons jump from the handle to you

Answer 1

Answer: Electrons jump from you to the handle.

Explanation: By walking on carpet, friction causes the rubber in your shoes to pick up electrons and then when you touch a metal doorknob you will feel a shock as the electrons jump from your body into the doorknob.

Answer 2

Answer: Electrons from the door handle jump onto you.

→ Remember, only electrons can be shared, so there is no way protons nor neutrons could "jump" onto you.

Why exactly does this happen?

When you walk through the carpet, you get charged, because of the friction  caused by your shoes while walking. So, when you get charged, the electrons on the door handle interact with you.
