Electric current is sometimes incorrectly defined as simply a flow of electrons What is wrong with this definition?

Electric current is the rate of flow of electrons.
AnswerA more accurate definition of electric current would be that it is a flow of electric charges. While current flow in a metallic conductor is, indeed, a flow of electrons, in other conductors -such as electrolytes- current flow may be a movement of ions. So, it would be more accurate to define current in terms of charge flow, rather than in terms of electron flow.

What two things are always equal within an atom?
The number of protons in the atom's nucleus and the total number of electrons in the electron shells of that atom.
Is an electric charge a property of just electricity or is charge a property of all atoms?
Atoms contain both positive (protons) and negative (electrons) electric charges. But in the vast majority of atoms these positive and negative electric charges balance, canceling and resulting in zero total electric charge. When electrons detach from atoms we generate electricity. Where there are fewer electrons there is a positive charge. Where there are more electrons there is a negative charge. When two places have different charges we get an electric voltage. When electrons flow from a negatively charged place to a positively charged place we get an electric current.
True or False. The imbalance of electrons in an atom creates a movement of electrons called the electric current?
true
When an electric field is applied to a metallic crystal the movement of electrons is?
Random
Do metals have electric conductivity?
Type your answer here... due to free electrons metals are good conductor
What is the definition for electric current?
Flow of electrons
What is the Definition of electric power and its formula?
The flow of electrons to create energy.
What is definition of electric current?
Current is the motion of electrons in a conductor being propelled by electromotive force (voltage).
What is the definition for positive charge?
having a deficiency of electrons ;having a higher electric potential
What is the definition of electricity not what it means?
An electric current is caused by the flow of electrons from one point in a circuit to another.
What electric forces between oppositely charged electrons and protons have to do with chemical reactions?
When metals react, they lose electrons to become stable and sometimes form a compound
What does an electric charge contain?
Electric charges contain too many electrons or too few electrons.
A shortage of electrons on a surface creates an electric what?
A shortage of electrons on a surface creates an electric what?
In a circuit electric current is flow of?
It is a flow of electrons.
Is an electric charge a proton?
No. Electric charges are generally electrons.
Electricity is the flow of?
The definition of electricity is the flow of charge. Usually our charges will be carried by free-flowing electrons. Negatively-charged electrons are loosely held to atoms of conductive materials. With a little push we can free electrons from atoms and get them to flow in a generally uniform direction. A closed circuit of conductive material provides a path for electrons to continuously flow. The charges are propelled by an electric field. We need a source of electric potential (voltage), which pushes electrons from a point of low potential energy to higher potential energy.
Definition of electromagnetic wave magnetic field?
Magnetic fields are produced by electric currents, which can be macroscopic currents in wires, or microscopic currents associated with electrons in atomic orbits
