ok, I have long been familiar with the negatron, what I was taught were the "electrons" in orbit around the nucleus of an atom. So where, in nature, do positrons occur?
I only recently heard of positrons, and how electrons i.e. negatrons can bond with positrons (which are also electrons, just positively charged) to form a photon, I'm just curious as to where these positrons are normally found.
What determines an electron to be either a negatron or positron? is it the spin?

Positrons are produced naturally by the decay of certain radioactive isotopes. Sometimes when a nucleus finds itself with an excess of protons, a process occurs which is the equivalent of one of the protons decaying into a neutron and an postron. The positron is emitted from the nucleus. This process is called beta+ decay.
The basic difference between an electron and a positron is their charge.

Over the years positrons have been everything from a floor cleaner to a dessert topping. Ha-ha. They actually started out as a misunderstanding. That lead to other misunderstandings. If you read through this link you might understand how misunderstanding lead to the most outlandish misunderstandings.
Benjamin Franklin was right on.

They were never needed by the original scientists that deciphered, checked and added the elements to the periodic table. These scientists only believed that there were protons and the protons were just balls of electrons. Held together by a bombardment of ambient radiation (high speed electrons). Hitting the object from all sides simultaneously.
This may depress you, however there were only a couple men on earth at anytime that were willing to devote their lives to science, and not do it for the money or power. These were the individuals that did know science. And in a matter of minutes they could change the course of humanity for years to come.

I have never heard the term negatron actually used in the scientific community, only electrons and positrons. You are in fact the first person I have heard using it.
Positrons are produced in the process of fusion and thus produced in the nuclear reaction that powers the sun. But it is unlikely that they get very far. Positrons are also known as beta radiation. So these were one of the three different kinds of radiation that were first detected coming out of radioactive materials, along with alpha radiation which is composed of helium nuclei and gamma radiation which is high frequency elecromagnetic radiation.

Electrons and positrons do not combine to form photons. They will annihilate like any antiparticle pair to release their energy in some form. If that form is electromagnetic radiation (i.e. gamma rays) the annihilation will produce at least TWO photons in order to conserve momentum (three photons are also commonly produced). But neutrino anti neutrino pairs can also be produced and if the postron and electron collide at higher velocities more massive particles can and have been produced up to and including the W and Z weak force bosons.

The electron has a negative electric charge and so its antiparticle the positron naturally has a positive electric charge. Since these are elementary particles your question does not make much sense unless you believe in string theory, in which case the difference would be something like their vibrational modes in a higher dimensional space being opposite one another so that these vibrations would cancel each other out if they came together.

In Nuclear Radiation Physics, a textbook, they briefly mention the term Negatron in regard to a negative beta particle. Granted, this book was initially printed in 1948 and its last printing was in 1972. I think the term has just fallen into disuse.

A Negatron is an electron with a negative charge, a positron is an electron with a positive charge. They are both electrons but by calling what were first discovered and called electrons Negatrons instead keeps the definitions a little more cut-and-dry IMO. Although it can lead to confusion since that term is not widely used.
and I REALLY don't like the term anti-electron sometimes attributed to positrons, although that does imply they are the "electrons" of anti-matter.

But it's true, actually. How would you call the negatively charged proton if not anti-proton? |

so then what is the difference between anti-neutrons and neutrons?

This has inspired alot of google searches for me!
anyway, do scientists know what the slight imbalance was that allowed some matter to avoid colliding with an equal amount of anti-matter that should have been made at the beginning of the universe? Instead of a universe of pure energy we have matter surviving almost certain annihilation caused by colliding with antimatter, but what is the cause of some of the collisions not occuring?

Neutrons are baryons and thus composed of three quarks. An anti-neutron contains anti-quarks. The quark composition of a neutron is up, down, down, and the quark composition of an anti-neutron is anti-up, anti-down, anti-down. Opposite helicity explains the difference between neutrinos and anti-neutrinos.

so quarks and leptons have electrical charge as well? and up has an anti-up counterpart which is a different charge? and there is a strange and anti-strange!
oh so confusing and strange!
so, even before matter and antimatter formed, couldn't the quarks and anti-quarks themselves have annihilated each other shortly after they existed?
