electron *

As the electrons move from one point to another, they can do work.

The electron is in one of those two states for sure.

Very little energy is needed to break the electron free.

Only electrons, he thought, moving from one place to another.

An electron can be here or there at the same moment.

An electron is a very small piece of matter and energy.

Do they believe there is such a thing as an electron?

Because of this, we really cannot tell where the electron is.

In that case the electrons did not move at all.

Only electrons were left, because there had been more of them to start out?

Instead, it is just the place where electrons are likely to be found.

None of the electrons even stay at a higher energy.

You may ask, why the charge of a single electron is not used?

The place they left behind is positive, and wants to get some electrons back.

Energy goes from the power plant to the moving electrons.

The electron remains the same before and after this process.

This means that there are two electrons in each energy level.

One way to deal with this is to find the charge of an electron.

But the experiment seems to see only the electrons coming out.

An electron does not stay in an excited state for too long.

You never need to replace electrons because they always come back.

Also typically only one or two electrons are so free.

First of all, the process for a "single" electron can be considered.

The electron is then in an excited state of higher energy.

Nothing on that screen, not a single electron, has actually moved from left to right.
