Antimatter is the mirror image of matter; an exact reflection. And as with any reflection, the image is inverted.

One of the most well known forms of matter are atoms. Atoms may be further reduced in to protons, neutrons and electrons. Protons have a positive electric charge of +1. Neutrons have no electric charge. Electrons have a negative electric charge of -1. Protons and neutrons may further be broken down in to components known as quarks, but electrons are a base particle, and cannot be divided further.

There are six types of quarks, known as "up", "down", "top", "bottom", "charm" and "strange". However, the majority of matter is comprised of up and down quarks. Up quarks have a positive electric charge of +2/3, and down quarks have a negative electric charge of -1/3. A proton is made up of two up quarks, and one down quark, which gives it its positive electric charge. A neutron is made up of one up quark, and two down quarks, which nullify its electric charge.

Now as for antimatter; its composition is identical to that of normal matter, but the electric charge is opposite. While a normal proton has a charge of +1, an "antiproton" has a charge of -1. Antielectrons have a charge of +1, in contrast to the -1 charge of normal electrons. Antineutrons still have no electric charge, the same as their neutron counterparts; however, the composition of antineutrons and antiprotons are different. They are comprised of antiquarks, which are the mirror images of regular quarks.

While a normal up quark has a charge of +2/3, an up antiquark has a charge of -2/3; and down antiquarks have a charge of +1/3, in contrast to the -1/3 charge of a normal down quark. There are also antiquark versions of every other type of quark.

Antiprotons and antineutrons are composed of the same antiquark ratio as their proton/neutron counterparts. However, as with electrons, antielectrons are a base particle, and cannot be reduced further.

Antimatter itself behaves much like regular matter. However, there is very little of it in existence naturally, and the only antimatter on Earth is synthesized in controlled laboratory environments. The reason for this is because of when matter and antimatter come in contact with one another, they completely annihilate one another, converting all parties involved in to energy.

Can elements be made out of antimatter?

Yes. Antimatter is only a point of view concept : we can imagine any object made of what we call antimatter. According to his point of view, we would be made of antimatter. Moreover, a number of large areas of the universe, that doesn't have any contact with each other, may be made of antimatter. we wouldn't have any mean to know from where we are.


Does antimatter have a nucleus?

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).

What are the disadvantages of antimatter?

The main disadvantage about antimatter is that it must be held away from its "ordinary" particle, preferably in a vacuum. This is because when they come into contact they completely eliminate each other. It's like if you add 1 with -1 it makes zero. However, if held properly, it can be excellent for research as we currently know very little about it. For example we don't know why there is so much more ordinary matter than antimatter.


Why antimatter can not be seen?

I don't know who told you it couldn't be seen. It couldbe seen, if there was enough of it in any one place to see. In fact, we don't absolutely know for certain that distant galaxies are not composed of antimatter (we're pretty sure they aren't, but it's difficult to actually prove this).
