The proton has a positive charge and the electron has a negative charge.

Electricity is created when particles become charged. Some particles become positively charged while others becomes negatively charged. Particles with opposite charges attract each other while particles with the same charge repel each other.

Since the electrons are in constant motion, occasionally an electron will escape from its atom and joins another atom. The atom that the electron ...
