What else can I help you with?
In an atom of antimatter what would be the charge of an electron?
An atom of antimatter does not contain any electrons. The equivalent of an electron in antimatter is a positron, which has charge +1.
Why is artificial antimatter less volatile than natural antimatter?
It isn't less volatile, it is exactly the same. As soon as an electron (for example) meets an anti-electron, they will both disintegrate - whether the positron (anti-electron) is artificial or natural.
Is an electron negative?
Unless its positive, in which case it would be a positron which is antimatter.
What are the antimatter equivalents of an electron a neutron and a proton?
Positron, antineutron, antiproton
How much does one gram of antimatter?
Anti matter does NOT exist. As soon as it is in contact with matter which is anything ; solid , liquid , gas, they are both annihilated. You can think of antimatter as protons with a negative charge and electrons with as positive charge. So Proton^+ Proton^- = Annihilation (??? Energy) Electron ^- + electron^+(positron) = Annihilation (???? Energy).
Who first synthesized antimatter?
The first synthesis of antimatter was achieved by Carl D. Anderson in 1932 when he discovered the positron, which is the antimatter counterpart to the electron. Anderson's discovery provided experimental evidence for the existence of antimatter.
Are positrons negative or positive?
Positive, positron's are the antimatter equivalent of an electron and therefor the charge is reversed.
What are positive electrons in science?
A positive electron is called a positron and it is a form of antimatter. It has the same mass and typical properties as a normal electron, but it has the opposite charge.
When matter created gravity as antimatter why not create anti-gravity?
"Antimatter" is not negative mass. Mass is a positive quantity for both matter and antimatter. So gravity is always attractive, even if one of the masses in the relationship happens to be antimatter. If such a thing as negative mass exists, then the forces between it and a lump of normal mass would be repulsive ones. Antimatter is observed routinely, but no evidence of negative mass has ever been observed. When matter & antimatter annihilate energy is released per E = mc2 where m corresponds to the sum of their masses. If the antimatter had negative mass then instead of a positron/electron annihilation releasing energy corresponding to twice the electron mass (as it does) the mass of the electron and negative mass of the positron would cancel resulting in no energy release (this does not happen). This proves that both matter & antimatter have positive mass, without even referring to gravity. As they both have positive mass their gravity will be attractive not repulsive.
What is a type of radioactive decay that involves emission from the nucleus of a high speed antimatter particle that is a counterpart of the electron?
This is beta decay, specifically beta plus decay. The beta particle that appears is the positron, which is the antimatter particle of the electron. Links can be found below for more information.
IS POSITRON IS NUCLEON?
No, a positron is not a nucleon.The term nucleon is applied to one of the two constituent particles that make up the nucleus of an atom. Those are the proton and the neutron, which are baryons.Whereas, positrons is a subatomic particle having the same mass as an electron but with an electric charge of +1 (an electron has a charge of −1).It constitutes the antiparticle of an electron. We don't see antimatter particles of any kind hanging around long in our "reality" here. (They "combine" with their antiparticles, and mutual annihilation will occur.)Should we investigate an antimatter universe, the positron will orbit the nucleus of an antimatter atom, just like the electron does in the atoms we look at. Naturally the nucleus of an antimatter atom will be composed of anti-protons and anti-neutrons.
Why does antimatter anihilate matter and Would a positron anihilate a muon or a quark?
A positron is the antiparticle of an electron; in other words, it is an alternate name for the "anti-electron". Therefore, a positron would anihilate with an electron. I am not sure about the "why".
