Electron volt is unit of

Charge is characteristic of electrons and protons. It is associated with a variety ofelectric properties. The magnitude of charge on an electron and on a proton is thefundamental value of charge, e = 1.6 × 10−19 coulombs, where coulombs (C) is the unitof charge. The charge on a proton is positive, while the charge on an electron isnegative. When grouped together, the charge on an equal number of protons andelectrons will cancel each other. However, if an object contains more protons thanelectrons or more electrons than protons, the object will have a net charge, q or Q. Thevariable q is typically used for a small charge, such as a point charge. The variable Qis typically used for a larger charge, such as the charge on plates. Charge, like matter, isconserved. Although the amount of charge remains constant it can move to anotherlocation or to another object. Although masses only attract one another, charges arecapable of attracting and repelling each other. Opposite charges attract one another,while like charges repel
