exact, whole number amount of energy needed to move an electron to a higher energy level

Magnetic fields do, because there's no such thing as an isolated magnetic "pole",

and a magnetic line always starts and ends at opposite poles of the same

magnetized object.

But electric fields don't. You can easily have a bundle of isolated positive charge

over here and a bundle of isolated negative charge over there, whereupon the

lines of the electric field start on one bundle and end on the other bundle.

But electric field lines can also exist in closed loops, and they do that in radio waves, where the electromagnetic field propagates with an electric field component and a magnetic field component, and they both form closed loops.

an increase in current, hence increased power and increased heat.

diamagnetic

Magnetic fields can be created by charges or the flow of current.

You would need to be standing on some kind of electrical insulator, such as a rubber mat, or on very dry ground.

false

Use the electronegativity chart to determine the type of bond that will form between this pair of elements.
