Can electrons exist on their own?

When you shine light on a cathode it emits a free electron
- nineteenthlyLv 73 months ago
Yes. A tube-based TV or monitor uses a beam of free electrons to make the picture, for example.

Sure, why not?
They are chemically attracted to positive cores, but if those aren't available, they can be magnetically bottled.

No they are created as per Gods law

There is a basic law called , charge conservation-- so for every negative charge in the universe , there is a positive charge.
But those charges don't have to be in the "same place" at the same time

Sure they can. And they do.

The electron is the lightest particle that can carry an electromagnetic charge of -1. Therefore, it cannot break down to anything smaller.
As far as we can tell, it is an elementary particle (it is not made up of smaller parts).
There are bigger particles that can carry a charge of -1 (muon, anti-proton...) and they can break down into smaller units (with the electron being one of the breakdown products).
The anti-particle to the electron (the anti-electron) is called "positron". It is the same as an electron, except it carries a charge of +1.
If an electron was to meet with an anti-electron, they would annihilate each other, liberating the energy of their mass in the form of photons, usually two photons of 511,000 eV (electron-Volts, a unit of energy used for very small quantities of energy, at the atomic level).
However, since the number of free positrons is very small (compared to the number of electrons), the probability that a given electron would encounter a positron at random are extremely small.
Therefore, in almost all cases, an electron, left to itself, would continue to exist on its own. It would likely be captured by an atom and would end up orbiting that atom, but it would still be an electron.

Every Atomic Particle canDaylight is lit up by Photons
We have Proton Stars
Our Days are brightened by Photons from the Sun
Our TV's and this Computer is powered by Electrons
What a Bonus it could be if we could Harness Lightning

a CRT is lit up by beams of electrons. A static spark is a flow of electrons through the air, as is a lightning bolt.
If you took a cubic meter of outer space, you would find lots of electrons just floating around.
plenty of other examples...
