Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called 'charge' being moved from one surface to the other. Dec 31, 2018
G. Johnstone Stoney he word "electron," coined by G. Johnstone Stoney in 1891, had been used to denote the unit of charge found in experiments that passed electric current through chemicals. In this sense the term was used by Joseph Larmor, J.J. Thomson's Cambridge classmate.

Explanation: Remember than electrons carry negative charge, and so if there is an EXCESS of electrons, there'll be more electrons in the object than the number of protons, and so the object will carry a negative charge. On an atomic scale, those are called "ions", and negatively-charged ions are called anions. Apr 24, 2018

Electrons do not move along a wire like cars on a highway. Actually, Any conductor (thing that electricity can go through) is made of atoms. ... If you put new electrons in a conductor, they will join atoms, and each atom will deliver an electron to the next atom.
Electrons and Electricity Breaking the atomic bond between an electron and its nucleus requires an input of energy which causes the electron to overcome the electromagnetic force constraining it and thus flow freely.
Electrical energy Kinetic energy is motion; it is the motion of waves, electrons, atoms, molecules, substances, and objects. Electrical energy is the movement of electrons. Everything is made of tiny particles called atoms.
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions.
An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor. In the circuits using metallic wires, electrons constitute a flow of charges.
An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.
