How does a neutral object become negatively charged?
AIt loses some electrons
BIt gains extra protons
CIt gains extra electrons
DIt loses some protons
Answer & Solution
Correct answer: C. It gains extra electrons
1. Protons sit locked in the nucleus, so the number of protons in an object stays the same.
2. Only electrons move when everyday objects are charged by contact or rubbing.
3. Adding electrons gives the object an excess of electrons and a negative overall charge.
4. Removing electrons leaves the object electron deficient, which makes it positive instead.
