I heard that a neutron is both a positive and negative charge ,but...?

Question

doesn that mean you can creat an artificial nueton if you somehow fused and electron with a proton.

Answer 1

The simple answer is that you can indeed make a neutron by putting together both a proton and an electron. However, these two don't have quite enough energy to form a whole neutron so you have to have a bit more energy from some source.

In other words 1 electron + 1 proton < 1 neutron

For example with enough velocity you can strike them together and the energy of the motion can make up the difference. This process can actually occur naturally when a proton absorbs an inner orbit electron in a process sometimes called K (electron)capture (which is funtionally equivalent to the emission of a positron and similar to Beta+ decay but with only a neutrino being emitted instead of a netutrino and a positron). This doesn't typically happen though. Typically, it happens the other way around when a neutron in an unstable isotope breaks down (Beta- decay) which leaves a proton while an electron and anti-neutrino are emitted.

It is actually accurate to say that a neutron has both positive and negative charges since these are not actually distributed evenly across the "body" of the neutron. In other words, its a bit like a water molecule which although neutral is more positive where the hydrogen atoms are and more negative where the oxygen atom is.

The most extreme example of what you are talking about is a Neutron Star. If a star has enough non-fusible material to have a very high gravity after it goes nova it will collapse. Then the high gravity squeezes the atoms until the electrons combine with the protons and form a core of nearly pure neutronium which is even denser than collapsium (degenerate matter core of a white dwarf) which has a weight of many tons to a teaspoon.

Neutronium is usually referred to as neutron degenerate matter and it has been theorized that higher pressure than this could result in quark degenerate matter which would be even denser. It would be difficult however to think of this as regular matter. There is also a theory that greater than this density could result in preon degenerate matter. However, no one has yet shown that quarks are made of preons.

Answer 2

Neutrons outside of an atom often "decay" into a proton and electron. It is likely that you are right but I think Neutrons are generally believed to be made from several quarks. This might be because the universe doesn't seem to like collisions so much as sytems like orbits (on a planetary scale) and propagation style órbits'on the subatomic. What i mean is trying to put an electron and proton together would have a very high probabllity of making hydrogen but there might be a percentage of ártificial' nuetrons.

Good question, you are no idiot but i love the avatar.

By the way (for the other answerers) I can't think of anything that is considered nuetral that isn't because of having both positive and negative their effects cancel out. But that doesn't mean that they are not there.

Answer 3

An electron can fuse with a proton to produce a neutron. A Neutron is generally considered neutral. :-)

Answer 4

A proton has a positive charge, a electron has a negative charge, and a neutron has no charge charge. The word neutron means neutral, no charge

Answer 5

Yes As a matter of fact within an atom they keep changing from proton to neutron and viced versa

Answer 6

A neutron walked into a bar and asked how much for a drink.
The bartender replied, "for you, no charge."

Two atoms walking down the street, one says "I think I lost my electron."

Second asks "Are you sure?"

First replies, "I'm positive."

A Neutron has no charge, positive or negative.

Could you build one? Well...

Answer 7

neutron have net zero charge.so, it may be posible to fused e & p.

Answer 8

Um, I heard a nuetron had no charge... not both.
