electric charges
Protons and electrons
Electric charges are the fundamental property of matter that causes electromagnetic interactions.
Particles carry positive or negative charge—protons positive, electrons negative.
Opposite charges attract; like charges repel.
This force holds atoms together and powers everything electrical.
In everyday use, electric charges often refers to accumulated static electricity: The electric charges built up on the balloon made her hair stand on end.
