Antimatter is composed of antiparticles in the same way that normal matter is composed of particles. Consider that atoms are composed of protons, neutrons and electrons. An antimatter atom could be composed of anti-protons, anti-neutrons and anti-electrons (which we know as positrons).
There are no positrons in the nucleus of any atom. Positrons are anti-electrons; they are antimatter. They could be said to be the antimatter equivalent of the electron, and, as such, they would be present around the nucleus of an antimatter atom as the electrons are present around the nucleus of a "regular" atom. Positrons can be produced in atomic nuclei by some kinds of radioactive decay, and they can be observed to be leaving a nuclear reaction called beta plus decay. But the positron leaves the nucleus of an atom as soon as it is created. It does not (cannot) exist in the nucleus of an atom.
All protons have a positive charge. The antimatter equivelant to the proton, the antiproton, has a negative charge. Every element of matter (hydrogen, helium, etc.) has an equivalent antimatter element (antihydrogen, antihelium, etc.) and just as every element of matter has a proton in its the nucleus (which, again, is positively charged), every corresponding anti-element has an anti-proton in its nucleus (which is negatively charged). There are also theoretical "hybrid" elements (called exotic elements of atoms) consisting of both matter an antimatter components, such as a proton and antiproton orbitting each other (this is called Protonium).
An antihydrogen is an atom of the antimatter equivalent of hydrogen, or the antimatter equivalent of hydrogen as a collective.
The founder of antimatter is considered to be the physicist called Paul Dirac in 1928-1930. He created a mathematical equation which predicted the existence of antiworld made out of antimatter.
Initially the 9g of remaining matter would survive. Each particle of antimatter can only annihilate with one other particle of antimatter. At this point the 1g of antimatter would cause an explosion equivalent to that of 200000 pounds of TNT. Causing both groups of matter and antimatter to be obliterated.
No. Every atom has a positively charged nucleus surrounded by negatively charged electrons.Unless you are talking about antimatter. The atoms of antimatter have negatively charged nuclei and surrounded by positively charged positrons
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.

But the positron leaves the nucleus of an atom as soon as it is created. It does not (cannot) exist in the nucleus of an atom.
The parts of the atom found outside the nucleus would be the electrons, or positrons if the nucleus of the atom is made of antimatter. The Heisenberg Uncertainty Principle shows us though that the electrons aren't found just in the space outside the nucleus, but in a probabilistic cloud, partly inside the nucleus.
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.
They can DEFINITELY breathe antimatter
This would be, by definition, antimatter. It would equal the total energy output of regular matter.

Previous answer "The existence of antimatter is just a lower less advanced form of dark matter" this is completely wrong, Antimatter is quite the opposite of 'normal' matter. It is made up of positrons that orbit around the nucleus in shells and have a positive charge. Anti-proton (a proton with a negative charge) and neutrons stay the same as they have no charge and are in fact neutral. dark matter is simply matter that doesn't give out light
