@guthrio,

Hi guys :)

I nearly found what i wanted to know:

"
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. There are two-types of electric charge; positive and negative (commonly carried by protons and electrons respectively). Like charges repel and unlike attract. An object with an absence of net charge is referred to as neutral."

..


"Electric charge is a conserved property; the net charge of an isolated system, the amount of positive charge minus the amount of negative charge, cannot change. Electric charge is carried by subatomic particles. In ordinary matter, negative charge is carried by electrons, and positive charge is carried by the protons in the nuclei of atoms..."
