Antimatter is not found on the periodic table of elements. antimatter is the same as normal matter, except only the charges of the protons and electrons are switched. Meaning a proton is instead a negaton a negatively charges proton, and electrons are positrons - positively charged electrons. Protons and negatons, electrons and positrons weigh the same thus any matter composed of those would have the same number or atomic weight and would have the same count of particles, except instead of counting protons and electrons we would be counting positron and negatons. The same number would appear - for instance the hydrogen atom consists of one proton and one electron - an anti-hydrogen atom would consist of one negaton and one positron. The anti-neutron exists, it does not have an anti-neutral charge, however it is composed of anti quarks. The anti-Periodic Table of elements would read much like the normal Periodic table of elements - until we looked at net charges of the particles. Some do have a positive or negative charge as a whole, and that would be reverse depending on which side of the equation you were looking at.

Its not on the periodic table

They are on the anti-periodic table. "At the moment physicists are having enough difficulty just taming antihydrogen, the simplest possible anti-atom. Can we ever expect them to make antihelium, and then organic antimolecules made from anticarbon and a whole anti-periodic table, too?" "As for our chances of making anything more complex, Frank Close, a particle physicist at the University of Oxford, is pessimistic, saying it will take a billion years, give or take. "It depends on how long the human race lasts," he says. It seems that our best bet for spying more exotic elements of the anti-periodic table is to look up at the sky - and hope that somewhere antistars are busy churning them out for us."

There are a couple of accelerators that have managed to produce very small amounts of ant-matter. No one has been able to "identify" much of anything about the stuff.

It has an unlisted number because it only shows up periodically.

What kind of antimatter?
