Describe electric charge

Is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. Two types of electric charges are positive and negative.

Most electric charge is carried by the electrons and protons within an atom. Electrons are said to carry negative charge, while protons are said to carry positive charge, although these labels are completely arbitrary (more on that later). Protons and electrons attract each other, the archetype of the cliché "opposites attract," according to the University of Georgia’s website, HyperPhysics. Conversely, two protons repel each other, as do two electrons.
