Questions and Answers

What happens to an object when it receives an electron?

It loses its atomic structure.
It gains a negative charge. (correct)

Study Notes

Electric Charge

Every object is made of tiny atoms
Atoms have three parts: electrons (negative charge), protons (positive charge), and neutrons (neutral charge)
If an object gains electrons, it has a negative charge
If an object loses electrons, it has a positive charge
An imbalance of charges creates static electricity
Charges can move if there is a difference in electrical potential (voltage)
