Because the positive charge of the protons in an atom are cancelled out by the negative charges of the electrons in the atom.
Atoms have NO electric charge, only ions have (+ or -)
Electric current can be started by closing a circuit, allowing the flow of electrons. This can be done by pressing a switch to complete the circuit. To stop the flow of electric current, the circuit needs to be opened, typically by opening the switch, which interrupts the flow of electrons.
molecules
It has an equal number of protons and electrons.
No, running an electric current through copper does not change the identity of the substance. The process may cause the copper to undergo physical changes, such as heating or electrolysis, but the chemical composition of copper remains the same. The atoms of copper retain their identity throughout the process.
In order to change an electric current, you must first change the conductor, doing so will change the flow of atoms which will change the electrical discharge.
A chemical reaction can break the chemical bonds that hold atoms together. A change in temperature can also do it, as can an electric current.

electrons
False. Electric current is the flow of electric charge (usually carried by electrons) through a conductor, not the flow of atoms.
it is nothing but electrons of atoms of that element that connects the electric current.
Particles in an atoms nucleus which do not have electric charge are Neutrons.
Correct
Electrons.
molecules
Cations.
